I just got a new 2 month old Katahdin buck lamb a couple of days ago. I'm trying to integrate him in with two year old Boer doe goats. So far I have had to keep the goats out of the pen with him because every time they're allowed in they chase him & butt him. Does anybody have any tips on how I can get them used to each other? I will be getting two ewes in about a month as well. As soon as we get our fence put up in the field we plan to graze them together so I need them to be able to get along. Is this a territorial thing that they don't want to share their space or what?
