My wonderful BA hen Nigella has been losing weight for about a month now. I didn't think much of it, but came back last night from a week-long trip to find her severely emaciated (her face even looks gaunt) and unable to walk properly. The other chickens all seem fine. Nigella seems to have a full appetite, and her droppings look normal. If it matters, she started losing weight right after a really heavy molt. Could she have worms? Feel free to direct me to a thread that's already been written - I looked around, but couldn't find any. Thanks!
