I purchased two sets of baby peas at an auction, Now they are about 4 to 5 mo old not sure on sex yet. If they are brother an sister will they breed and have fertile eggs? and will the baby chicks be normal?
Yes they will breed and have fertile eggs. They will probably not produce fertile eggs until they are two. The babies will be normal. Although the possible long term consequences of inbreeding are beat to death on poultry forums, most of the breeding groups of poultry owned by hobbyists are closely related including many brother/sister combinations.
