The floor is about 12" above the ground and there are 2x4s framing underneath so I guess there will be about 10"-11.5" clearance under the coop. Is that enough for full size chickens (we have an ameraucana, astralorp, BO and a SLW) to go underneath? If so it would probably stay nice and cool in summer and I will put wire all around the bottom. Boy it is taking a long time, two coats of primer and two coats of topcoat on everything is wearing me out! Those expensive ready made coops don't look that expensive any more.
