I am wondering if, for the money, you might get some help, buy plywood and 2x4s, and build one that would have better ventilation. Just my first thought. I like the dimensions, and it looks pretty nice.
I agree, Go to the coop thread and look at what you can do for less money and if you have friends or family that are handy with hammer and saw? endless idea... plus lots of ventilation. this is geared towards chickens but applies to all poultry..
