I just brought in 16 spanish/boer mixes. 14 pregnant (or thought to be), 1 wether and 1 buck. One of the older mothers has developed a knot, hard and about the size of a golf ball at the base of her neck, in the front on her chest. It feels hard, not squishy and doesnt move around. She doesnt appear to be in any discomfort, even when you touch it. All the hair is there. Anyone have a clue? We are newbies and have only had 3 boers for a couple of months, and no problems, unless you count to gorging on the deer feed....lol.
