It looks like a good start.
I can not tell if you have anything over the top or not but hawks and owls will come in if it is open. Also racoon are good climbers and could climb in.
Also remember fox coyote and dogs will dig in if there is no parimeter barrier down in the ground.
The chain link will keep bigger critters out but permit rats and weasels.
I dont mean to bum you out, but i have learned these lessons the hard way myself, and see similar resulting stories of carnage on this site every day.
Your coop looks to small, are they securely locked in that at night?
