As some of you know, a couple of days ago one of my hens was bitten on the head my my chihauhau mix. Her wound is fine now, but the blood that leaked into her nostril is causing her to have a hard time breathing. Her breathing sounds kind of like a goose when it hisses at you (that's what I thought it was when I first heard it) and she breaths with her mouth slightly open. She is starting to get kind of listless, and I am worried that she won't make it. Is there anything I can do to help her? Thanx!
