Hope you have lots of enjoyment from your new chickens! I live on a rolling mountain slope & have all of the usual mountain predators; it's wild & active up here. I would love to 'free range" but alas, I love my chickens too much to lose them; so, they are locked into their coop every night, the food area is locked up every night & the coop is within a large top & side fenced yard which is mostly within our regular yard which is fenced. Sounds like you have most everything covered to keep them safe. The only things that I didn't notice is if you will lock them into their coop nightly & have considered wire on the ground also; consider laying & attaching 2x2 ( the like) fencing on the yard ground (covered with dirt) in case a predator digs thru the night or day & gets in. So smart that you'll have it burried a foot in the ground too. One side of the yard is exposed to the forest & small animals are always tunneling under to get in. Have fun, chickens are a blast!
Some Dads can be a little harsh sometimes, it may be his way of making you use caution & also to be realistic & prepare for the worst so you aren't hurt too badly. My hubby's like that; it erks me, but makes me stronger. The end result is that I just think & work harder to prove him wrong & make my plans come out better. Besides, I know he cares, he just comes off that way; after all these years, I'm wise to that "big softy's" ways. He even built me a lovely coop, after much protest & grumbling. So funny!
