If you continue with that set up, agree about elevating ... Raise up on tile blocks & go with DLM. Agree, no matter what the box says if you're getting egg layers, thinking 3-4 will be your limit and a tight fit. Minimum 4 sq ft in the coop per chicken, 10 sq ft per chicken in the run. Something more open air would be good for your weather (you may want to update your profile with your location, so we don't have to ask in the future) ... This is what I came up with for my area (hot/humid & wet) ....
