Yesterday a neighbor's dog got into our chicken trailer. 3 hens. One was killed, one appears to have a broken wing but otherwise ok. The third bird got it pretty bad. Lacerations on the face and neck what looks like a cracked beak. It's been 24 hours and she is wheezing heavily, eyes often closed or rolling to the back of the head. It looks like she can't moved her beak/jaw at all. I can't imagine her eating food anytime in the near future and she is not drinking water either. Also, lots of diarrhea this morning. She is still moving around a bit - all of her injuries are above the neck. Is there anything we can do to help this hen or should we take her out of her misery? We can't afford a vet.
