I have a hen that I found in her house when I opend the chickens door to let them out to free range. She was getting up and like she was dizzie kept claspsing looked like she was passing out! I picked her up and looked at her and she had 2 black eyes her whole face was swallon. and 1 of her legs she can not stand on at all and the other one she can't stand on right. She keeps opening her mouth gasping for air. And when I picked her up you could feel her hart rate going super duper fast. I do not know what to do. I currently sepperated her from the others. Can I do anything eles for her do you think?
