I had a guest at my home on Saturday, and there little Terriour decided he could smell something and took a run for my back yard ran all the way out to the back 2 Acres went into the bushes where my Chickens like to hang out when they are running about. Anyway long story short, it got ahold of one of my hens feathers were flying everywhere, when I got her to where I could take a look at her she was limping very badly could not get her to come to me for some time, he pulled out all her tail feathers and I did not find any puncture marks on her but he must have bitten down hard enough to cause some internal damage to her leg, her leg now is backward almost. She seems fine I have confinded her to a small cage so she can rest the leg this week, What on earth should I do I do not want her to suffer and I am not sure if it is worth a vet bill could be rather costly? She can not walk without a limp now I do not believe they show signs of pain ??? Chickens that is? do they? When I pull on it to get it strait she tends to fuss a bit so obviously that hurts. What to do?
