I had that happen some years ago. We weighed everyone. Several ewes with 5 months old lambs had gained weight. We were pleased thinking that after weaning they had put the weight back on. 2-3 months later they lambed again! This is when we had just a few ewes, were not separating the lambs to wean them, and were running the ram with the flock. LOLthe rest of the sheep stayed the same except one ewe who gained (damn paperwork is in the barn). I've been thinking she may have a lamb, and with the weight gain that may be happening.
"A bunch of panels, a sort gate or two . . . . " Tell yourself that as you add equipment to your wish list!Those sheep handling systems are so awesome looking, but way more than I need. A bunch of panels, a sort gate or two and I think I'd be happy
