Hi!
Your coop may be a bit tight, but unless it gets too terribly hot in your area it should not be a problem.
Your run is generous in size. Don’t worry about the ground unless it has dangerous sharp objects or things chicken should not ingest.
I live in the desert there is no grass here so I supplement the girls’ diet with some scratch, raw veggies, mealworms, etc. A hanging wire basket with greens packed in it, chicken treat balls, and whole

tied up just above head height all give them something to do besides scratch and peck. I only give these things in mid to late afternoon so
I’m sure they are getting high protein, non-GMO, layer crumbles. Oh, I also supplement with cactus fruit and any type of vegetation they will eat, but no jipsomweed or tomato plants.
If you put metal flashing over the nest boxes, most of the poo will slide off and it will be easy to clean. Bantams do perch, but if you get silkies, they’ll need a droppings free area on the coop floor. Some will perch but only if the roosting bar s low enough.
Best to you!
Regards…
