We plan on another layer around bottom sides and a into the ground. Had to hurry up and finish up because we were able to find a few more birds and the old duck house that was here was a mess lol. For now we have traps set up and three dogs loose in yard all day as well as two walks a day with them in the woods around property. Only lost one duck to an animal so far and it definitely sucked. She wouldn't come in coop and was roosted on a board that was touching the hill behind it. From the tracks a raccoon just walked up the board while she was sleeping and jumped her. Thanks!The coop construction looks great. I don't know what additional securities you have around the property, but I want to make sure that you as well as anyone looking to this as an example in the future are aware: Chicken wire is great for keeping birds in, but not for keeping predators out. Many predators will rip right through chicken wire with their claws or teeth. 1/2" hardware cloth is recommended for smaller predators (fox/raccoon/coyote). I have seen it recommended that the hardware cloth either be sunk 1 foot into the ground, or laid around the pen as a 2 foot skirt in areas with digging predators. Also raccoons can figure out a simple bolt latch fairly quickly so if that is the only line of defense, it may not be adequate. For more information and maybe specifics for your area, I would browse through https://www.backyardchickens.com/f/13/predators-and-pests.
I lost 2 ducks to predators early in our stewardship (https://www.backyardchickens.com/t/883393/r-i-p-ebony-and-belle). It was devastating. Since then, we have been much tighter on security and have had no further incidences.
