I am new at raising goats and have three. I just got our newest addition Saturday. I have a 4 month old doe and a 3 month old billy. The newest is 7 weeks old. I'm not sure how to safely bring the newbie into the pen. I brought her in and sat with her and the other female chased her around and around in circles butting her. I separated them and put them on different sides of the fence. I tried again today but only putting the new one (Casey) in with our baby billy (Oliver) and he was sort of blowing his nose and making these noises with his tongue out and chasing her. Is this normal??? I am at a loss and have put Casey in the main pen by herself to get used to it and the other two separated inside in a smaller pen. Any help would be great!
