I have had chickens both on wire and a solid floor. I liked the wire because poop thing falls through to the ground. No bedding to buy, no coop to clean, no shoveling very clean especially with XROCKS After my crop of HERITAGE TURKEYS the wire got so stretched that I had to put 1 x 3 boards spaced 3 inches apart on top of the wire. This floor works well and is still very clean. The solid floor works well for LAYING HENS and other small birds and letting the bedding build up for winter is a big plus. The solid floor doesn't work with XROCKS there is just to much very wet poop to shovel, cleaning the coop of poop is an never ending job.
My hen coop a 7 x 16 foot truck body has a "second floor" a wooden built in place cage 3ft x 7ft with a solid floor that I use for day old chicks it's 36 inches off the coop floor and is very easy to clean and work on. As the chicks get bigger they go into another cage on the floor under this "second floor"
