Chicken wire basically only keeps chickens contained. It doesn’t keep the “bad guys” out - larger predators like raccoons can rip through it, and 1 inch holes will let in the smaller ones, like snakes that will eat your eggs and baby/young chickens. Or minks/weasels even, which can kill an adult.
To keep the predators out, you ideally use 1/2 inch or smaller hardware cloth OR some people make due with a larger strong fence with 1x2 inch holes with chicken wire over top. But that isn’t as good, so I would recommend using hardware cloth for at least the bottom half of the wall.
You also have to address digging predators (rats, opossums, etc) by either digging a trench under your coop and having the hardware cloth go underground or laying a couple feet of it around the coop and attaching it to the ground with tent stakes or similar (or place rocks over top). And it should be attached to the edge of the coop.
If you stay with chicken wire for the run, just be aware it is a risk and you will likely lose some chickens at some point. And I would at a minimum use hardware cloth to secure the coop part for sleeping and always lock them in it at dark. During the day you are less likely to have issues - mostly hawks and dogs in the daylight.
I hope that helps? It is a beautiful build!!!
