We have 6 ewes, who were wormed (with Combinex for worms and fluke), thinned down, then flushed. They are ready for the ram on Monday. Today we removed the sponges and gave them a PMSG injection. 5 put of the 6 had put weight on nicely, with a good but not excessive layer of back fat. One has stayed thin, with visible hip bones and a really bony back bone. She looks significantly thinner than the others. She is still penned up inside the shelter, and had 1/4 bucket of ewe lamb and goat mix, which she wolfed down. To check her eating we left her water and 2 buckets of hay to eat. About 4 hours later she had not eaten any hay. The questions are: why has she not gained weight like the others? And is there anything sheep can get that would put her off eating grass / hay? We plan to keep her penned for now, to check the hay goes down, but it seems a bit odd she has stayed thin. Many thanks.
