NEED HELP QUICK, RABBITS JUST GAVE BIRTH?

I suggest you put a low barrier across the opening upstairs to keep the kits contained until they are two weeks old. Their eyes will be open then and they will be wanting to explore. Also put in plenty of hay so mum can make a big nest for her young and maybe cover the front of the hutch with a blanket if she seems to be getting stressed. I don't think noise should worry her any more now then it ever did.
