Hi all. We have a Lleyn ewe 5 yrs old that went down hill a couple of months ago, with AB's, vit drenches etc she made a recovery. However she is still very thin, has self weaned her lambs (not surprisingly) and often has a stained green lower jaw which is presumably her cud spilling out. We checked her teeth and there is nothing obviously wrong there. She grazes well and looks bright enough. Any ideas what could (cud??) be causing this please?
