Hi, I have my hens in a roofed pen and because I'm only on the allotment every other day leave them to put themselves to bed and get themselves up the henhouse is fully enclosed in the pen and as safe as I can make it.
Haven't had any problems so far after a year's chicken keeping (finger's very crossed when saying this). They have the biggest water holder I could find so they can't run out and the same with the hopper for their pellets. I let them out morning and evening for a free range which they love doing, they keep close to home and are easy to herd back in again with the promise of something tasty.
If there were any problems, several of the allotment people have my telephone number so could report back to me.
Hope that helps
best wishes
Sue
