You cannot breed Pokémon in the base Cobblemon mod as of version 1.8.1. Putting two Pokémon in a Pasture Block will not produce an egg. The 1.8.0 update from September 2026 added Alpha Pokémon, TMs and new habitat structures, and neither the 1.8.0 nor the 1.8.1 entry in the Cobblemon changelog mentions eggs or breeding. Earlier versions of this guide incorrectly described the Pasture Block as a breeding machine and applied mainline Pokémon egg mechanics to Cobblemon. We have corrected that information.
The official Cobblemon Pasture Block page describes a place to let Pokémon out of PC storage, not a nursery. The official advancements page still labels egg-collection and egg-hatching triggers as available once breeding is added. This article describes the base mod first. A server or modpack can behave differently when it adds a breeding add-on such as Cobbreeding, which the Cobbleverse modpack uses and which is covered below.
What Does a Pasture Block Actually Do?
A Pasture Block lets you send Pokémon from your PC into an area of the world. You can interact with them and recall them through the block. The official wiki says the default capacity is 16 Pokémon, and the Cobblemon config includes settings for pasture capacity, update frequency, wander distance, and Pokémon per chunk.
To use one:
- Craft and place a Pasture Block.
- Open its interface and select Pokémon from your PC.
- Let them roam nearby, then recall them through the interface when finished.
There is no vanilla Cobblemon step in which you pair two Pokémon, wait for an egg, or hatch one from the Pasture Block.
Does Pasture Block Breeding Work?
Not in base Cobblemon. Pasture Block breeding only exists when a server or modpack adds a breeding mod. The one behind the eggs in Cobbleverse is Cobbreeding, a side mod that describes itself as a way "to add Pokémon breeding early", before Cobblemon has its own system.
Cobbreeding extends the Pasture Block. You put compatible Pokémon in the same pasture, press the button that turns breeding on, and an egg may appear later in the nesting area at the bottom of the block. Pokémon from different owners can breed together in one pasture.
Cobbleverse and Servers With Eggs
The Cobbleverse modpack includes Cobbreeding. Cobbleverse 1.7.42 from July 2026, the newest version on Modrinth when we checked in September 2026, ships Cobblemon 1.7.3 with Cobbreeding 2.2.2 on both the client and the server. That is where Cobbleverse eggs come from.
To get and hatch an egg with Cobbreeding:
- Put two compatible Pokémon in a Pasture Block and turn breeding on for that pasture.
- Come back later and take the egg from the nesting area at the bottom of the block.
- Keep the egg in your inventory. The hatch timer only runs while the egg is in a player's inventory.
Cobbreeding also adds its own versions of several mainline mechanics: IV inheritance with Power items and the Destiny Knot, nature inheritance with the Everstone, egg moves, Poké Ball inheritance, and a Masuda-style shiny boost when the two parents have different original trainers. The authors note that some features work a bit differently than in the main series games, so read the Cobbreeding page before you plan a breeding chain.
Breeding times and shiny boosts are config values. Cobbleverse ships its own Cobbreeding config, so a Cobbleverse world can use different numbers than the defaults listed on the mod page.
Are Eggs, Ditto, and Egg Groups in Cobblemon?
Pokémon species data may include egg groups, and items familiar from the mainline games may exist. That does not mean base Cobblemon currently implements egg production. In particular, Ditto is not a universal breeding partner in the base mod, and there is no built-in egg timer to configure.
If you have seen eggs on a server or in a modpack, they come from an add-on, not from Cobblemon itself. In Cobbleverse that add-on is Cobbreeding. On other servers, ask the owner which add-on provides them and check that add-on's documentation. Compatibility rules, timers, inheritance, and permissions are specific to the add-on and should not be assumed from the mainline games.
Do Destiny Knot, Everstone, or the Masuda Method Work?
Not as egg-breeding strategies in base Cobblemon, because there is no base breeding system. Claims that a Destiny Knot passes five IVs, an Everstone passes a nature to offspring, or foreign-language parents enable Masuda-method egg hunting do not apply to an unmodified Cobblemon installation. A server add-on may define its own mechanics; verify those with the server owner. Cobbreeding is one add-on that does: it lists IV inheritance with Power items and the Destiny Knot, nature inheritance with the Everstone, and a Masuda-style shiny method, as described in the Pasture Block breeding section above.
Similarly, do not assume a Shiny Charm or egg-specific shiny odds are available just because they exist in another Pokémon game. The official config reference lists shinyRate for spawned Pokémon, with a documented default of 8192 (a 1-in-8192 chance). Your server may change that setting or use an add-on. See our Cobblemon shiny hunting guide for the distinction.
How to Build a Strong Team Without Breeding
- Catch or trade for Pokémon with useful IVs. Check the Pokémon summary or the tools your server provides before investing training time.
- Train EVs through battles. Choose species that award the EVs your build needs and track your progress.
- Use a mint for the desired nature's stat effect. Cobblemon mints change the stat effect without changing the Pokémon's displayed original nature.
- Hunt shinies through spawns. More eligible spawns mean more independent chances at the configured shiny rate; egg-hatching routes do not exist in base Cobblemon.
Our Cobblemon IV, EV, and nature guide covers the stat-building side in more detail.
Berry Farming Is Separate From Pokémon Breeding
Berry trees can be cultivated and mutated in Cobblemon. This is a different mechanic from breeding Pokémon. Plant berries on farmland, harvest mature trees, and place compatible berry trees next to each other, not diagonally, for a chance at a mutated berry. Preferred biomes and mulch can affect yield or mutation chance. Check the official Berry Tree guide for the current combinations; do not use Pokémon egg-group rules for berry mutations.
Notes for Server Owners
If your server uses only base Cobblemon, do not advertise a breeding area or publish egg timers. Pasture settings such as defaultPasturedPokemonLimit, pastureBlockUpdateTicks, pastureMaxWanderDistance, and pastureMaxPerChunk govern roaming Pokémon, not egg creation. The official config list is the source for current setting names.
If you install a breeding add-on, name it in your server guide and document its actual version, compatibility rules, egg timing, IV and nature inheritance, shiny rules, and commands. Those details can change independently of Cobblemon.
Cobbreeding is required on both the server and the client, so every player needs it installed too. Cobbreeding 2.3.0 is the release for Cobblemon 1.8, and the 2.2 releases are for Cobblemon 1.7, so update the two together. The authors publish it on Modrinth and say they will not upload it to CurseForge, so a CurseForge upload under that name is not theirs.
On your own Cobblemon server you decide whether breeding is part of the game: run base Cobblemon without eggs, or add Cobbreeding to the mods folder next to Cobblemon.
Common Questions
Can you breed Pokémon in base Cobblemon? No. The official wiki still marks egg collection and hatching as future breeding-related features, and the 1.8.0 and 1.8.1 changelogs do not add breeding.
Will two Pokémon in a Pasture Block make an egg? Not in base Cobblemon. The block lets Pokémon from PC storage roam nearby; it is not a daycare. With the Cobbreeding add-on installed, compatible Pokémon can lay eggs once you turn breeding on for that pasture.
How do you hatch an egg in Cobbleverse? Cobbleverse uses Cobbreeding. Take the egg from the nesting area at the bottom of the Pasture Block and keep it in your inventory; the hatch timer only runs while the egg is in a player's inventory.
Does Ditto enable breeding? Not in base Cobblemon. A server-specific add-on might support it, but its rules need separate verification.
Can I use the Masuda Method for shinies? Not in base Cobblemon, because it requires eggs. Hunt spawned Pokémon instead, or check the rules of a breeding add-on on your server. By default, Cobbreeding gives a Masuda-style shiny boost when the two parents have different original trainers.
Can I farm berries? Yes. Berry trees and their mutations are supported, but they are unrelated to Pokémon eggs.
