My ewes are due to start lambing on 18th Feb, with the majority lambing through March (and an odd straggler due 3rd week of April... she returned after 6 weeks, the day before the ram came out
). They are coming in this weekend for crutching and we were planning on heptavacing at the same time- but the majority of the ewes would then be outside of the 4-6 week pre lambing window.
They are coming in again on the first weekend of Feb so I could do them then, that's 2 weeks before the early lamber, but it would cover the majority of the ewes then that will lamb in March. Thoughts?
