If you are lucky, some of the hawthorn does not have prickly branches, and is nice on your hands if you pick it. Thing is, with prickly things like hawthorn, and wild rose, which goats love, its best to let them pick their own, otherwise if your give them the branches to help themselves, sometimes the thorns get stuck in feet, udders etc.
Funny story now, well it was not funny for my friend at the time. one of his nanny goats got a swollen face. Took it to the vet. Vet said he would have to keep it in and operate on this lump on its face. Named a big price. Friend is a farmer, he said no way, and took goat home. Got his wife to hold the goat, and he looked carefully at its face, and there was a large thorn stuck. He got some tweezers, removed the thorn, and by next day goat was much improved!!! He was always careful with his money, and I still smile to think how sick he would feel had he paid the vet, and then found out the damage was just a thorn he could remove for nothing!!!
