My 11 year old Daisy has lost some teeth this winter and has become very thin. I an giving her a soft mash of ewe pellets each day and they all have hay ad lib. could anyone recommend a really good brand of sheep pellets ( or would lamb creep be better) to build her back up. They have an energy lick in field - I only have 11, all getting on a bit, but the other 10 are really fit. a bit overweight if anything.
