I am considering constructing the floor out of construction cloth. Or at least that's what I have heard it called. It's the small 1/2" square mash wire. They can walk on it, poop through it and in the Florida heat, it should keep the inside cool. I'll design it so if we ever do get any cold weather, I can cover it to help keep them warm. This way I will be able to just rake the poo from under the coop and toss it in the compost pile. The nest boxes I'll build on the sides of the coop with an exterior access door for egg removal and cleaning access. I plan to have a ridge vent and a small cupola mounted on the roof for ventilation. With 2x2 roost boards extended across the coop. Trying to incorporate rotating the run and garden area in with the coop. There is a lot to this.
