New Coop and Design

[Summerford]

This is what I'm looking to have it look like. It will house 12 hens. Any input is appreciated. It's going to be 4 ft. tall. 8 ft. wide and 12 ft long. The coop is going to be 3 ft deep and 3 ft tall and 8 ft. wide.

I recommend making it tall enough for you to stand in.
It is a convenience you will appreciate when cleaning out litter, etc.
The chickens also LOVE to roost high up at night...and it's warmer up there in the winter.

We made ours last summer - it is 8 ft. tall at the roof peek, and 5.5 ft. x 6.5 ft. There are 3 nesting boxes inside.
We also have 12 birds. Here is a picture - I know it is nothing like your design - just wanted to show you the height.
Our son is 6'6" tall and the primary care-giver. He is very happy that he can get inside and move around while standing erect.
