(Feathyr here - I forgot my password and ended up having to use mom's account.) Two days ago, my eight (8) month-old Welsumer pullet began showing signs of illness. Her tail droops, she's lost quite a bit of weight and she eats litle. Yet, she continues to drink, forage, talks to me, and is highly alert - an otherwise healthy bird. She quit laying about a week ago, which isn't unusual as most of my girls are the middle of molts. I've twice inspected her for tumors, bound eggs, mites, Mareks, worms, with no results. She sometimes has difficulty breathing, so I've given her a little over an eyedropper-full of Duramycin-10 to help with that. I'm currently trying to force some yogurt into her, and she shows interest but doesn't eat. I'm stumped; never seen anything like this. Any help is greatly appreciated, thank you in advance. - Feathyr EDIT - Forgot to mention that she seems to be in some pain when she walks, so the rooster may be responsible for that. No other chickens are acting this way.
