I was always led to believe that if you left the lambs in the ewes would not come into season on time.
I may be wrong but mine come out into 2 groups Tups and ewe lambs.
The ewes are run onto a tight pasture to dry them off.
The ewe lambs are taught to bucket feed and more importantly drink.
The Ram lambs go onto the best grass to fatten.
The ewes are put on better grass about now to get back into condition.
The tups are checked over ready for the breeding season.
and it starts all over again
