Hi Scotsgirl. Hope lamb recovers. The ewe with lumpy udder sounds like mine - lumps mainly around the teats and very sore. Not mastitis (see previous posts on this) but she had the same problem last year by what my son can remember. However, that said she is a good mother and always produces good lambs,usually twins. I think all things have to be considered before culling a ewe who has other attributes. Good luck.
