if you are sure they have no means of escape, what breed to you have? how big are they ? as even the most smallest of holes are tempting to a bun, i have 2 escapoligists so id never let them free range but the giant cross i had loved the freedoom, you have to watch carfully what they nibble, the cross i had nibbled at pretty much everything but, after a while didnt touch certain plants,and as he was huge i figured a small amount would not hurt him, i would not reckonmend this to others spesh if you have small buns, i think there is a list somewhere of what is safe for buns to nibble and what not. best to write down what you have in your garden, and look up. if you are going to be out supervising, you should be ok, just check everything gaps between your house and next door garage if you have one,if you have gates for you drive etc cover with chicken wire,check your pots too mine like climbing in to nibble my herbs :roll:
