We have four hens, and two baby chicks. We knew our old coop wouldn't be sufficient for 6 chickens so I designed this new coop and DH and I built it. We're very proud of it
Pictures and details are on my blog.
We've made four modifications so far:
1) stapled wire mesh inside the window so we can leave it open in the summer
2) DH made a ramp / ladder for the girls to get up onto the perch as they were being silly about it
3) We put a lid on the food tub, with a hole cut in the middle so they can still eat but not scratch the food out everywhere
4) DH put a board across the middle nesting box as the girls like to nestle up against a wall when they sleep and didn't want to do so against the wall over the door
Other than that it's worked out great and we're pleased with it.
