Hi there, I'm sure your buns will soon settle. My latest two girls aged probably two and three, were used for breeding. Until they went into rspca they only knew being in a cage in a shed. I've had them 8 weeks and it's been a worrying time. They like to come out now but need the protection of their large hutch with a snuggle box when they get spooked. To start with they were terrified of everything....wind, rain, birds. The seagulls flying over really scared them. Next doors trees rustle and whistle. As time goes on they are slowly improving and I'm sure your buns will be fine too. It's just time and patience. Good luck.
