I have 8 chicks right now. The oldest female is the only one the smells weird. She doesn't smell like dirty chick smell, almost like rotten eggs. The others you can hold without gagging at the smell. She loves to be held so I feel bad I don't hold her because she smells so weird. She smells around the face, I think. I don't go around smelling chicks, so I don't know for sure lol. Why is she the only one that stinks and what can I do about it?
