Hi, I'm hoping someone can help me. I have a 3 yr. old hen who has an injured leg. I looked out the window earlier and saw my Saint Bernard standing over my hen and he snatched her up by the wing. I gave the command for him to "drop it" and he did. She was wet with his drool so I wrapped her in a towel and held her until she calmed down. I have her separated from the rest of the flock for now. There are no open wounds. She is limping on her right leg and she complains when I move it in any direction. Should I make a wrap for it, or just leave it alone and let it work itself out? How long should I give it before I need to worry?
