We have a couple of this years lambs who were small to start with but were then growing on OK. Now however, they are losing condition fast and losing muscle. One barely seems to have the strength in her front legs and prefers to kneel down to eat. Both are eating, not scouring, have been wormed, flaked act. with no obvious signs of anything (no lameness in the legs, just lack of muscle).
I suspect we are going to lose them (or have to have them PTS) but they don't appear to be in any pain or discomfort, just lack of strength. Can't find anything in the books so looking for suggestions!
