I have a white crested polish chicken who is normally my spunky girl. For three days she's been sort of sleepy and not herself. She's lost weight, hasn't been eating much at all, but she is drinking. She went to the vet yesterday to confirm no peritonitis or egg binding. Blood work has been sent off. Her tail is lowered down and her butt feathers are all fluffed up. She moves around but is just slower than usual. Droppings look normal, maybe slightly greener than usual. Doesn't appear to be contagious, no other birds showing signs. Ruled out MD. Just looks uncomfortable on her backside. Worms? Any suggestions or similar encounters?
