I’ve just noticed that the roof is chicken wire. I don’t know what predators you have around your area but foxes (and I imagine coyotes etc) will be able to chew it and get in with relative ease. It looks like you have a lockable coop inside the run so you should be ok a night but here in UK we get loads of foxes during the day and I had a couple of close calls before I enclosed a large area for them with electric fence. The hardware cloth like you have on the sides would be a much better option. You have a nice set up there though, your girls will be happy.
