Getting started
To breed any Pokémon, a ranch block is required.
After placing down a ranch block, two Pokémon from the player's PC (not the player's party) can be put into the ranch block, where they will begin to wander within a 9×9 block area around the ranch block. If these Pokémon are compatible for breeding, the breeding process will begin. Before 7.0.0 the ranch block could hold up to six Pokémon and multiple breeding processes could occur concurrently within the ranch block if there were multiple pairs of compatible Pokémon.
