Its been quite some time since I looked at this thread, and I feel compelled to update it.
The Chicken McMansion lives! We adopted out the last three hens from our first flock earlier this spring, to make way for five new Rhode Island Red hens. The older girls were down to producing 3 eggs a week between them, and it was time to make a change. Our new girls have all come into lay in the past month, & we are getting four eggs a day reliably, some days five.
The coop has held up tremendously. I repainted the outside this spring, and had to make a new window for the weather end, as the old window frame had rotted. Other than that, the coop has been remarkably maintenance free. I add more sand to the run a couple of times a year, along with a good shot of DE. I built an outside sandbox for the girls, and they love that nice warm sand for dust baths.
The coop has proven very easy to clean. The big door on the end gives me clear access to the whole inside. The porch paint I used to paint the walls inside has not worn one bit, neither has the garage floor epoxy on the floor. The corrugated fiberglass roofing has also been remarkably durable and holds up very well to the very gusty winter wind we get here. I fill the hen yard 2 feet deep in shredded leaves each fall, and the girls churn it into beautiful compost by Spring, which I share along with the eggs.
In the first full year the original flock laid, they produced 117 dozen eggs! I kept my egg logs from then, and it still amazes me how many and how large those eggs were! These days, the Farmer's Markets around here are getting $6.50/doz for large brown eggs, and $9/dozen for extra large! We're not selling eggs, but our family and friends enjoy the bounty with us. Half a dozen fresh eggs makes for a great way to meet a new neighbor too...
My neighbor down the street, who has enjoyed our eggs for a couple of years, built himself a coop this spring and now has five hens of his own! He studied what I did and it encouraged him to take the leap. Like us, if you did not know he has chickens, you could not tell, and we like it that way.
Raising my own backyard chickens has proven to be one of the most rewarding, satisfying things I ever decided to do. I am constantly amazed at what social creatures chickens are, and how much pleasure I get from taking care of them; along with the amazingly delicious eggs the produce.
All continues well with the McMansion...
Cheers!
