This is the first time we have raised chickens so excuse me if this is an ignorant question. One of our chicks has a bald butt! We washed it and applied some A&D (hence the greasiness) but was wondering what it could be? As far as we can tell she is in good health, eating, drinking and active and we have not caught her or any of the other chicks picking at her feathers. I'm not sure how long this has been going on but she was born 2-22-12 so she is only a few weeks old and last week she did not have this. Any ideas? All of the other chicks have great coverage so I don't know if it could be a bug?? Help please! Thank you!!
