The 10x12 Alumi-Coop is perfect for my flock. Mine arrived slightly damaged from the loading and unloading during shipping. Wendell was quick to respond, and I got the replacement parts right away.
The coop set-up was straight forward and easy enough. I did it alone, but I would recommend 2 people. A couple of the steps were a little tedious all by myself but would have been a breeze with a partner.
My chickens love it. They get all excited when they see me reach for the handle now, because they know new grass is coming.
They aren't laying yet, so I can't speak to the nesting box, but it looks like it will work very well.
The waterer with the cups is working great. Best waterer I've ever had for my chickens, and I've had a few. This one stays clean, and just exposes enough water for them to get a drink, the rest stays closed off and is bug and algae free.
The feeder, I may still need to play with. My chickens aren't grown enough for me to mount in on the outside, so I mounted it on the inside, and they are making a mess of it. I probably just need to adjust how much comes out, the hopper opening is adjustable.
Moving it is easy for me, but I'm a big guy. My wife, who is petite, found it too hard to move. Same with my 8-year-old son. I think it's a very well-designed mechanism to lower the wheels and lift the front. I don't mind moving it at all.
Last year, my whole flock got killed one night as a pack of stray dogs found a weak spot in my home-made coop/run set-up. This Alumi-coop is essentially Fort Knox. I don't think there are weak spots, everything is made of strong metal for the walls and thick tarp for the cover. Digging would be a dog's only option, and I don't think there is a good solution to that, considering the coop is mobile.
