This morning my husband went to check on our chickens and came across one acting out of the ordinary. One of our Cuckoos (not sure what a mix of Cuckoo) was sitting in run and seemed off. She is usually skittish and if you go her way will skit off in another direction, but today my husband walked right up to her and she did not move, she also let him just pick her up which never happens. She has a full crop, but he says she seems to be very light like shes got no weight on her. She is not eggbound that we can tell and just seems subdued......Any ideas?
