I have a BO hen who I found this morning sitting by the fence away from all the others not moving. I went over and stirred her up to notice that she was limping. She was not using her right leg. I immediately picked her up to investigate, and noticed a large wound under her right wing, it looked like it happened last night as it was dry and not bleeding. I put some vetricyn on it as that is all I have and put her with food and water by herself. What else can I do? I don't know if t was my rooster being rough or something got her? ive never had a predator problem before but my neighbor has 3 semi outdoor cats. Plus I know there are opossums and coons around. Please let me know if theres anything else I can do. Thank you.
