Hi all, I received some "mystery" chicks. I know a few are araucanas. However they came from Mt healthy Hatchery. I was told the others were brown rocks. Assuming they meant partridge rock. I am thinking they are speckled sussex. My question to you is what do you think? Right now the chicks are mottled brown/black. Some have white feathers mixed in. When do speckled sussex get the speckling pattern? How about the partridge pattern, when does the green feathering show? I've never raised either of these breeds before. Thanks for your help! Cris PS- sorry!!! I just realized I put this in the wring section.
