Hello. We are just starting out our herd. We started with a couple ewes which both turned out to be pregnant. We got a ram early on and he’s been with them the whole time. One ewe gave birth to a ram 3 months ago and the other ewe had a ewe lamb one month ago. Now both rams are aggressive with the ewe that has the one moth old lamb. They won’t allow the lamb to nurse. They bother her all the time. Only have the one pasture set up for them at the moment. Have been separating the mom and lamb in the shelter so the lamb can nurse. Any advice is appreciated.
