Hi guys. I have a hatchery salmon Faverolle hen who has been dropping weight like crazy. She used to be a fatty. She does not seem to be interested in food and when I pick her up her crop is always empty. She is the only hen I have with any symptoms. I run a closed flock. She has not laid an egg since November. I wormed her with worminator about 4 days ago just in case and dusted her real well with sevin dust. Made her scrambled eggs, which she didn't care for, and forced some nutri-drench in her. She seems really thirsty and drinks all the time. She has no discharge of any kind. Clear eyes, nostrils, no coughing or breathing problems. Poo is normal, if a bit liquid, but i assume thats because of the crazy water drinking. I can't explain the rapid weight loss other than she just has no appetite and I don't understand why. What am I missing here? Any advice would help. Thanks in advance!
