Hello, As you can see we are still in the process of building our coop, and this is our first time getting chickens! We are getting 6 Rhode Island Reds. Is there such a thing of to big out a coop? We plan to give the chickens about half the space of the inside, and use the other half for storage. We live in colorado, so we thought it would be best to not have such a big area for the unpredicatble winters. Is this a good size for only 6 chickens? Also one other strange question: Are chickens sensitive to bright colors? This used to be an old play house and the walls are painted pretty out there. Thanks so much!!
