Hi everyone! I have 3 sheep, an ewe and her twins, and was wondering if their behavior was normal. They are almost as tall as her at 4 months, although not as heavy, they weigh 40 pounds each and she weighs 75, definitely not a meat breed. When they go to nurse they are not gentle at all, lifting her up and headbutting. This caused her to only nurse for two or three seconds. Would this cause any problems for them in the long run?
