We hadn't thought of that, they've been in it for two and a half months now and I dedicated a broom to the coop and I sweep it out via the back door, but I was thinking that the floor would need to be treated or replaced eventually. And ya, hubby gave them a window and a sky light! This weekend he bought the girls solar lighting as well. We just picked the book "chickens for dummies" so I'm sure he'll be tweaking his design a bit.
My hubby builds LEED Certified Multi-Family and Single Family low income housing here in the valley, he was a custom home builder for most of his 30 year career, with the last 6 being devoted to the Coalition. His first project with the Housing Coalition finished 4 years ago, is still winning awards, 15 by my count so far. He's one heck of a green builder!
Thank you for the complements! And suggestions! He may know his buildings, but chickens are new to us!
