Those prefab things can be cute, At least that one appears to have enough ventilation at the top where it belongs. But that's a lot of money. You could build a simple 8x8 shed and large run for that much, with water and electricity. Coops don't need heat unless used as a brooder, and that's way too much light for anything but your use, briefly, if you have to tend to the chickens at night. I have to wonder how long those thin legs would last, and whether 4 are enough.
