I went out this morning to find one of the two remaining bred ewes had delivered twins at some point late last night or early this morning. Both were clean and dry and had been up to nurse. Later this morning, the last ewe decided it was time, though she didn’t actually manage to lamb until after noon. She also gave me twins.
So the statistics for the 2017 lambing season are:
14 bred ewes
10 ewes bred by Red ram: 5 singles; 3 sets twins; 2 sets triplets – total 17 lambs (10 ram lambs; 7 ewe lambs)
4 ewes bred by White ram: 1 single; 2 set twins; 1 set triplets – total 8 lambs (6 ram lambs; 2 ewe lambs)
I lost one of the first set of triplets, a ewe lamb, so have 24 lambs on the ground: 16 ram lambs and 8 ewe lambs. I’m still watching the smallest of the last set of triplets as he hasn’t reached 6 lbs yet but so far he is alive and the ewe appears to have sufficient milk for all three lambs.
Addendum (03/13/2017): Not unexpectedly, I lost the smallest of the most recent set of triplets.
