Yesterday something attacked our flock of chickens, they're still young (8 weeks) so it might have been our cat. One was dead and three I found scattered, but one was missing. I couple of hours later I heard a fuss and went to check and my toy poodle had found the missing girl and cornered her, she had her head stuck on the wiring to a cage. I got her out and she seemed pretty stunned but moved fine once I brought her in. I put her in the coop and she seemed fine. This morning she didn't come out with the rest of the girls and was on the nesting box instead of the roost. I have her in a box inside now, she didn't give me her usual sass when I picked her up and she's obviously not feeling well. But there's no blood and she let me check her over, I don't see any bruising. She did try to perch on the box but seemed a bit unbalanced (that could have just been because a box isn't a very good perch). Is there anything I should be looking for?
