I have a RIR that is almost 5 years old. I noticed her comb was dull and she was slow to come out of the coop two mornings ago. Once out she didn't go and eat. Just stood there. She also had a poopy butt, with some green colored droppings. I started the flock on duramycin and put ivermectin topical on because I've seen fleas in the yard. I wormed them a few months ago. I was going to tube feed her today because she didn't seem to be eating. But I got her to eat some canned cat food mixed with some kaytee exact baby bird food on her own. I gave her a bath today in some Epsom salts, mostly to clean her butt off. Is there anything else to be done?
