I have a 3 month old Nubian buckling who was weaned at 8 weeks. We have noticed a large lump around the area where the neck meets the chin. It is soft, not hard. He doesnt seem to be sick or anything, he acts normal. Could it be a milk goiter? Is it possible that this could occur with a kid that has already been weaned? Will it go away on its own? Also, he was bottle fed as a baby with milk replacer. Could it maybe be iodine deficiency? If so, how would I treat it? Could it be CL? Swelling from CL are usually hard and dont get that large though, correct?
