I went down to the pen this evening to check on the hogs and noticed one of them with a bad limp. She still gets around the pen just fine but she is putting little to no weight on it. I threw some old bread in there and she went over and ate some of it. After eating she went right back to laying down. Since she is still getting around and eating and drinking, will she be ok? I just dont want her to stop eating and start losing weight. The hogs are raised on pasture not concrete. What do you all recommend?
