Crazy chicken lady
Yes, definitely swap that chicken wire for hardware cloth. Even a chihuahua could probably bust through chicken wire! The actual size of the coop is pretty big! It looks like the roost bars are next to the nesting boxes?Where are you located???? You definitely have some ventilation going. What direction is that coop facing? Not much protection from blowing weather.... unless you HAVE NO blowing weather....
I would change out that Chicken Wire for hardware cloth. Chicken wire isnt much protection from predators.
I think chickens could get into those nesting boxes, but personally I'd lower them just a bit. There's no real need for them to be *that* high. Plus, they are higher than the roost bars! That means the chickens would probably try to sleep in the nest boxes. Also as others said, lower the nipple waterer a lot! It needs to be maybe around 8-12" off the ground for chickens, but that would still be too high if you ever wanted to hatch baby chicks. If the water set up still works, I'd try to use it, but you could always disregard the original system and try something else.
How long has it been since chickens lived there? Personally I'd deep clean and sanitize as best as I could. I'd be worried about disease among the old flock... some diseases can live in the soil for a long time.
