Oldshooter; I gotta see your set-up, sounds great. I found that the best color on a chicken is white. Most daylight predators, hawks and coyotes tend to neglect them. At night, any opening in the coup is a welcome mat to all predators.
Recently a couple of my Bantams hatched out some chicks. They run free and roost in my barn, but with a clutch of chicks they'll stay on the ground and a cat , fox , coyote can clean up on them easily. Well I found where one was hiding and during the day set a small dog tote box near her spot. After sunset I went to the barn and picked her and the chicks up and put her in the box and closed the door. Next night she was in the box. Then the second hen hatched out, and lo and behold I couldn't find her anywhere. But when I looked into the dog box to make sure hen #1 was safe before I shut the door, there was #2 in the box also. Every night they're all in the box together . Smart chickens I'd say.
