Hi, I have a ewe who has multiple lumps the size of a large marble on her head, around her jaw and one near her eye! They seem to be getting bigger and increasing in numbers. There is no signs of a thorn and the skin isn't open. One burst today when we were catching her and a long sticky thread of puss came out, a greeny/yellowy colour. Her behaviour hasn't changed. Does anyone have any ideas what it could be? Thanks
