I have a 1 and a half year old black star cross hen. I also have 2 austrolorp hens, same age and 2 bantams. Also 3 large ducks and 2 call ducks. Everyone else looks fine. The black star hen started not moving her right wing about a month ago. Took her to the vet to look for injury. He found nothing. Then she started limping. She will jump up into the coop. Lately she is not moving much. She looks alert, but is losing feathers on right side wing. She cried when I picked her up, so is fighting back. What should I do? She was eating and drinking. I brought her in the house today. She is a pet, but I do not want her to suffer. I can take her to the vet again. I am not sure what to do.
