Today a couple of my hens got into a 10 second tiff and after that one of them seemed kind of shocked. She then began limping around. I put her in the coop and later found her panting (it's 90 degrees and humid here) so thinking she was over heating I took her in the house. She is eating and alert but still panting. Her vent is pulsing and tail up. She just passed an egg but still panting can't stand and seems restless. Any ideas?
