My RIR hen is not doing good. She has lost part of her comb,what's lefit is a dull red. She doesn't seem tohave any problem breathing and there is no discharge form her nose.She eats ok but not as much as she use to. She just finished molting a month ago.Any ideas?
Worms or mites/lice could be the problem, if you haven' already treated for them. You should consider answering the questions in the sticky at the beginning of this section.
ddawn is correct. Visually inspect them for lice/mites, especially around the vent area. If you've never wormed, most likely they have them but I suggest you take a fecal sample to a vet and have them check for worms, they'll also check for cocci. The fecal test shouldnt cost much at all.
