I've noticed my bantam silver laced Wyandotte hen is looking unwell I'm very worried about her. I thought that is just a bug or something that she would have for a little while but she isn't getting better, her skin is yellow and her comb and wattles are not very noticeable she stays back from everyone else and isn't very active she hardly eats and drinks I haven't checked for parasites yet and I haven't checked her poop yet either. Please help I don't know what to do and I'm really worried
