Aloha, this morning my dog chased one of my chickens and pinned her down with her head in his mouth. He didn't shake her and I got him to let her go after about 5 seconds... she ran off, but was bleeding a little bit from her comb, but that stopped after couple minutes. Other than that she seemed totally fine, but now won't really interact with her flock (4 others and she is in charge), and really wants to keep both eyes closed and just sleep... while awake she seem really stressed, breathes heavy but keeps eyes closed... then she falls asleep, breathing slows, her comb becomes pale... she doesn't want to eat or drink anything... but she can make noise, open her eyes, and move about fine, she just doesn't want to... is she just in shock? I have her in a safe place where they lay eggs away from everyone else. Has anyone ever heard of anything like this before? Any advice would be appreciated. She is a Barred Rock hen about 9months old. Thanks!
