Hey Sharon, glad you're enjoying your little flock. general recommendation for back yard flock is 4 s.f. of open space in coop per bird, and 10 s.f. in run per bird. Depending on they layout of your little coop, perhaps you could easily expand the space in there as well. As for treats: many flock owners give too many b/c it's fun to see the birds enjoy them. Too many treats often = low protein diet, high fat diet which can lead to behavioral problems as well as obesity. The bird develops a lot of visceral fat which can lead to reproductive issues. I limit my birds treats to a few extra garden veggies, all the weeds and insects they can glean from my yard. I save scratch for the times i need to call them back into their run. My flock gets fermented feed.
