Great ideas! I had an A frame 4 X 8 coop/run with 4X4 of the upper part of it closed off for the coop itself. We built a platform for it to raise it 3 feet higher, added a front door, and hatch door that locks down. Ladder leads up to the hatch door from underneath. Nothing can get into the coop itself in case any critters get into the run part. We have a replica of this same A frame coop and are going to build an 8 ft run (halved) to go between them and to join them (for asthetic purposes) to allow more run room for both coops. The coop isn't designed for more than 4-5 chickens and I will have 5 in each for my breeders. I know 5 chickens in there is not the usual 4 st per bird, but these are my breeder pens and the chickens will only be in there at night to sleep. All of my chickens free range in the afternoon.Florida Hen- If you are putting it up on cinders you need to be aware that that is the perfect crawl space for rats. Believe me they can chew into the bottom of a coop in just a few days once they start. I wouldn't have put it on the ground either for that reason May want to raise it a good 2' off the ground and give the girls a ladder to go up. Rats can climb the ladder but if you close the coop door at night they can't get in. Alternatively just build a small 'porch' for the girls to fly up to. Then rats can get up there at all. ;-)
