How big is the difference in weight if you don't mind me asking?We've been mobbing ewes and lambs up as soon as possible and rotating ewes and lambs to last 3 years, ewe weights at weaning have gone up and lamb weights at weaning have gone down, shifting them 1 to 3 times per day is to hard on lambs, they just can't compete with the ewes for better quality parts of the pasture when shift rapidly, next year we're going back to more mobs and shift them every 3-5 days.
