Here are the two girls that we haven't quite adopted yet with their present owner. I'm not brave enough to try this because the chicks I have seem to poop everywhere all the time without warning. Anyway, I'm not an expert, but the top one looks like a silkie... The other one looks bigger and similar, but I wondered if anyone had any ideas.
If you are feeding a medicated chick starter you do not need to be concerned about coccidia (BTW it does not contain any antibiotics if that concerns you). Good luck!
