I am not sure what an x-pen is. The shed needs to be fixed or something. It has holes from water damage, our yard used to flood heavily every summer for most of the summer then the city changed something and we only get standing water when we have serious back to back storms/hurricanes.
Last week, the daughter (she has severe ADHD, OCD and tourrettes)let the rabbits out while she was gardening,it got dark from rain clouds and it was evening. The boys are predominately white and easy to see and they hang at the door so they can zip in at will, Nutmeg is brown and white, not so easy to see in the dark. Hannah thought Nutmeg was in but never checked. It poured and poured, I noticed Nutmeg was not in her cage when I was feeding and watering them before bed ... it was pouring. I was hoping and praying she was in a bedroom, which she loves to sneak into so I searched and searched, waking kids up by moving their beds ... found the naughty bunny in the yard at 3 am. She was wet from hopping around in the wet grass and very dry on her back and head. I am her favorite person again.
The rabbits cannot get out of the yard, we have blocked all gates and openings with cage wire and there is nothing dangerous in the shed, just tiles, water skis, lawn mower and bikes. And plywood.
