At 12:30 this morning we were awakened by our chickens screeching. My husband quickly grabbed a gun and ran outside to find two dogs helping themselves to our chickens. One of the dogs ran off when they heard the back door open but the other had a fatal night. I caught these same two dogs at the coop door two days ago trying their darndest to get their breakfast, but I scared them off, so sorry to say I didn't feel to bad that it was killed. It didn't have a collar or anything so it didn't seem to have a very responsible owner. We thought they had killed two of the three but this morning when the sun was out and we could better assess things, I realized only one had died. After observing the chickens for a while, I could see that one of the survivors is injured. It looks like the dog snipped or bit it right under it's right wing. It can stand, although I did spot it stumble once, but now it's starting to hide in the corner to lay down. I highly doubt it will be able to get into the nesting boxes to lay (which I know probably won't happen for a while because of the trauma) or roost at night. Any recommendations on what I can do? Do chickens recover from these types of injuries? Should we keep it alive?
