You are keeping chickens the way most people do - getting the chickens first and worrying about secure housing afterwards. Read my post #4939 about Raccoons. Just because you haven't seen wild critters around the property doesn't mean you don't have any and Raccoons are probably the most troublesome because of their easy manipulation of digging and tearing. For protection from digging critters like coyotes, dogs, wild pigs, foxes, weasels, raccoons, oppossums, wild rabbits, etc, is your hardwire buried in the ground? If not, make a paver stone walkway or use property boulders to line the outside perimeter of your gate and pen frame. Cover the bottom half or all of the coop pen with 1/2 inch hardwire - you don't want sagging roof wire. Where's the perch for the chicken's to use? Yes, I agree you have tons more to do with upcoming hatchlings to add on top of everything else that's not done. I love that you want chickens but rodents will love entering that broody's ground nest to eat her eggs. Broody hens are so unaware that if a rodent is under her she'll just think it's a hatching chick. If you can swing recycling some old wood make a raised coop house and attach the pen in your photos as a run next to the new coop but modify the pen with 1/2 inch hardwire - 1/2 inch hardwire will be the MOST expensive part of the build but necessary for the hens' protection.
May I say that your coop is not "ugly" as you state - just unsafe for housing chickens. Hope you can swing more modifications to make the chikens secure.
