a neighbor dog attacked my 3-year old hen 10 days ago. There were several large deep bites on her upper back which are now healing nicely. I cleaned them out well, gave her oral antibiotics in her water, and there is no sign of infection. However, after about 2 days, she was unable to support her weight on her right leg. She moves around some using wings and her good leg. I cannot feel any odd lumps or breaks. Anyone had any experience with this? I have her in the basement with straw bedding, heating lamp, and rest. She is eating and drinking some, but not a lot. But pooping fine. She had already quit laying for the season.
