Good Morning. I have 3 hens that were attacked by a medium sized dog a few days ago. One seems fine. One is walking around, eating, drinking, laying...but she sounds congested...any advice? The third will walk a little bit but with a limp. She prefers to lie down. She is eating and drinking some...I can get near her to check her over for injuries and when I get close I am afraid I am causing additional stress. Help?
