moving home

hi all following sids suprise litter i realise that her hutch isnt going to be big enough for long. I have been gifted a huge hutch from freecycle at what age should i move mum n babies across to new hutch?was then going to leave them in there until mum was ready to be away and then put her back in her own hutch.i really dont want to disturb them too much as im terrifyed mum will eat or kill or abandon them.i havent picked babys up but hutch is getting wiffy thanks to the sunshine!
thanks in advance

Hello the new hutch sounds really good. I'm really sure but personally I wouldn not disturb them until they are bit older and can leave their mum.
