I need to separate my rabbits as she is pregnant and I have another hutch, how far away does it have to be so he can still see her, i was going to put the 2 hutch in like a L shape or is that too close
No, not too close. Just far enough so she can't nip his nose through the wire if she's in a bad mood (still have to name my buck, "Scarface" comes to mind...).
