Newbie here. Just got my first rabbits one week ago. A trio of silver fox. Want to try a colony. The book I bought on colony raising said start them together young. They are currently in a tractor type set up as I build my larger shed and run. It is roughly 4x10, has an insulated box at one end, 3 den boxes 12 x20, wire covered run, extra shelves to climb and rest on. They came from a breeder that used individual cages. Seemed to adapt well, and looked happy in their new space. The 2 does are now 9 weeks. The buck is now 12 weeks. This week he has become relentless constantly trying to hump the does. They don't seem to respond, ( but I can't always see them) have places to hide. I hate to put him in a cage alone. Is there a danger he will actually succeed while they are still too young? Do I have to remove him just to give the girls some peace? Will they accept him back into group living months later? Please help! I want the colony idea to succeed.
