hello! I'm new to this forum. We have backyard chickens and this morning a fox came and attack one of our best egg laying chicken. The chicken still breathing and looks like she is in a lot of pain. The beck is purple which is probably a hematoma from the injury. There are two small punctures in the neck. I don't know if I should put her out of her misery or wait and see if she can come out alive. I put neosporin on the wound and I have given her water with a small amount of infant Tylenol for the pain. What do you all suggest I do??
