the bunnies new run

well i build them a new run whhich attached onto their happy hutch from the side and they wont go in it all 5 bunnies are sat in the hutch i spend allthat time on it and they stay in their hutch. just there isnt enough room if they all stay in the hutch but i built extention of 8 ft by 3 ft but they wont go in whyyyy?????? but if they dont go in it then do i split them up cause a happy hutch is not big enough for 5 bunnies.. eekkk

I'd give them some more time as they're probably a bit nervous of the new space. You could try covering part of the run with a blanket so it feels more secure then put their food in there at the next meal time. That shoud temp them.

That's bunnies for you! Ungrateful little tikes. I would try the food idea too!
