I like that I spent the extra money and predator proofed the whole structure. That way I don't have to lock them in their coop at night. The ramp can stay down and they can let themselves out in the morning, as nothing can get into their run from top to bottom..
I think that's my favorite thing about our coop~run as well. We went out of town this weekend and never worried that anything would happen to the chickens. I also leave the pop-door open, so they can come out in the morning when ready. We built this coop with the run a couple of years ago, and the chicken never spent any time in the run,....until the past few weeks. A coyote came into the yard and got one of our favorite girls out free ranging. It's such piece of mind knowing I can keep them in the run and the coyote can't get anymore of my sweet girls.
Oh, I also love we thought to put a closet inside the coop. It have field fencing walls and door, so when I have a broody hen she can sit on her eggs undisturbed, but she can see the rest of the flock and they can see her. No reintroducing her or her chicks when she's ready to take her little one's out to be with the flock.
It's not big, but plenty of room for a nursery, and when not needed for a broody, it's plenty of room for storage.
