My neighbours dog was in my yard today - went right for the girls and caught one of my beautiful Speckled Sussex hens. Luckily we were able to get him off her in time, but she's badly hurt and very shaken. I think her leg is either broken or dislocated. It doesn't seem swollen but it's limp and she doesn't seem to be able to control it well or put weight on it. There is a significant puncture wound in her back. I have applied topical hydrogen peroxide to it and it doesn't look infected but I worry that there are more that I haven't seen. This particular bird isn't used to being handled so it's difficult to realize the full extent of her injuries. I plan on waiting until it gets dark and then examining her more closely. I have isolated her and have her inside. She's not eating and will only drink if I dip her beak in water. A more experienced chicken keeper friend says that I should put her back in the coop with her friends, that she will be less stressed around them. However I am afraid they will peck at her since she can't really move. I was thinking of keeping her in the cage but putting it back in the coop since she does seem really stressed inside. Any advice would be most welcome. I hate to see her hurting and will do anything I can to help her heal.
