If you click on the link to my page below in blue you will see my set up for my bantam cochins, right now there are 5 in there. I raised mine up to keep the rodents from building a home under it, so far so good, plus everything is within reach from the big door and clean out is easy, I have a short garbage can that I slide up to the opening slide everything out and into it then off to the compost bin. One other plus to this is there would have to be a lot of snow to keep me from getting in without shovelling my way in. I used a cat litter bucket for my first nest box, they seem to like it when they are young, but moved to the nests that I build a little bigger when they get older. My only regret, I didn't make it bigger. I am increasing my flock by leaps and bounds this spring and am in construction of a tractor and plans for a coop and run when the weather gets a little nicer. There are lots of folks who use 5 gallon buckets, I was planning on trying this out too (actually I have several 2 and 3 gallon buckets for that), just rig up some way to keep a lip on them to the bedding stays in and add some way to keep them from rolling around with the chickens inside.
