I have one boer that still has her undercoat. We brushed her the other day and goat a big handful of fiber. All my other goats have sleek summer coats, but this one goat still has a rough thick coat. High temps have been between 75 and 95 for at least a month here. I got her perhaps a month ago and she has had a worm problem which I am still working on. Should I be concerned about her not shedding yet? Does it indicate some other problem going on?
