We are here to answer questions.
1. how do all of you house your bucks?
My bucks have a fortress made of corral panels lined with cattle panels. There's an old chicken house (large) inside that for shelter.
2. will he be more determined to escape than a doe?
During rut and when the does are in heat, they are all determined. Bucks are bigger and stronger.
3. I thought goats were herd animals, can I house him alone?
He needs a wether or another buck with him. They will be mounting each other in dominance displays regularly. It doesn't mean they go both ways.
4. how close should I have him to the barn where the girls are?
At least two fences between. I've had through the fence breedings when there was only one net wire fence between.
5. will my girls try to get to him?
Yes. I had a doe OPEN THE GATE to let him out.
6. can I leave him out in the hutch all winter?
Depends. If he has a buddy, plenty to eat, and deep bedding, he ought to be ok.
