My chicken was attacked yesterday evening by what we believe was one of our cats, she seems ok except she keeps opening and closing her mouth and sticking out her neck. We think it was a cat attack because her feathers were all messed up and we have had chickens attacked by cats before and it looked very similar. We gave her some sugar water through a syringe and she seemed to swallow it good but still is doing the opening and closing of her mouth, it's been going on ever since we found her laying in the front yard after she was attacked. She also can't make any noise at all and can't stand very well. We checked her for cuts and scratch marks but couldn't find any, she is a pet chicken and we can't get her to a vet. Any suggestions?????
