Hello all, Needing some advice. I was going to try and use the area beneath the coop as a portion of their run both to try and conserve space in our small backyard and to provide them with some shade/protection from the elements. Question is, if the coop is 2' off the ground, will that be enough headroom for the chickens? Again, they will have another portion of the run with 3' to 5' of "headroom." Also, I will have an access panel on one side plus access from inside the run when I need to clean the shorter area. Then for the roost: I have read so many books and posts that now I'm confused. 1) How high should the roost be? Is 18" off the floor ok, or do I have to put it higher? 2) How far away from the wall should the roost be? I think I read 12" in one book and 18" in another. If 12" would work, that would be ideal (conserves more of the coop floor space for the hens). 3) How much headroom do the hens need when they are on the roost? Is 18"+ enough? What's the minimum? (BTW, there will only be one roost, about 4' long, 3 to 4 hens). 4) Finally, for those of you in cold winter climates, is it ok to position your roost on the north wall? This would be the ideal spot for ours, but I'm wondering if it would be too cold. It would be in front of two access doors to facilitate cleaning of the area; we'll do our best to insulate the doors and seal around them to minimize drafts. Coop will be wired for electric, and we'll use a heat lamp as necessary. I know this is a lot of questions, so thank you in advance for any help you can offer!! This site has been amazing so far--don't know what we'd have done without your help.
