Not sure what to do about my hen...I have 4 hens (all leghorns), the other 3 are fine. But this gal, she has been sick almost 2 weeks now...watery whitish diarrhea that is sticking to her feathers, her comb is folded and dark red/purplish, she hasn't been laying eggs. I've felt her belly, and I don't feel an egg in there. I've felt her crop, which seems fine. She is eating and drinking some but just looks sick and seems to be isolating herself from the others. When I've taken her out of the coop to clean her, etc., she just isn't very fiesty either. We have a coop that's raised and a penned area underneith it. Any ideas?
