OK, so our planis for a 10 x 6 coop. My idea for the interior layout is as follows: It is for 25 birds. (They will have access to a 1/3 acre enclosed run during the day) It will face almost due south (it's really the only way we can do it) The floor will be 2' off the ground to create a 10'6" x 6'6" enclosed pen beneath the coop (that will not be for sleeping, only for daytime access) saltbox roof (I think that's what it is)---back wall will be 8' above the floor, front wall will be 5' above the floor, roof will slant down from back wall to front wall. There will be guttering, but chickens will enter/exit the side with no access to the front of the house. we are going to use SunTuf polycarb corrugated roofing--looks like corrugated metal roofing, but it's transparent or translucent--they carry it at Home Depot Roof will overhang about 8" on the sides and 12" on the front South facing 10' wall will have a 5' wide by 3' high window Man door on one 6' wall, chicken pop door on the other 6' wall. Window that opens will be above man door. There will be a ramp for chickens to use. We will build a 3.5' wide nest box, 12" deep, with slanted board 15" above it and an outside access door. My best friend's chickens all nest in the same straw filled pig trough, and I'd save on lumber if I don't divide the box up. I figure, if that's how they learn, they'll just follow the program, yes? 2 roosts, one along each of the two 10' walls . I would like your thoughts on the following: 1. Deep litter method: for that size coop and 25 birds, how deep should the litter be? I only want to change it once a year. 2. Should we make the roof out of clear panels, which has 90% light transmission, or white, which only has 45% light transmission? I don't want to make it too sunny in the coop on a sunny day, unless they prefer sunny. They could always go underneath for shade... 2. I plan to use a wood stair railing for the roost poles. Since I have heavy birds, I'm thinking of keeping it 20" up, and my nesting boxes about 12' off the floor--is that high enough above the boxes? Is it low enough for the big birds? And for 25 chickens, how long should each roost be? 4. Is that an OK setup for feed/water? I can install hooks in the walls to hang them, or put them on a platform to keep them out of the litter--which is better, and how high should they be? 5. I think it's a good idea to have the people door be framed with chickenwire in the top half that can be boarded up to make a solid door in winter--sound OK? 6. I think the people door should swing out, so as not to swing over the litter or be obstructed by the roosts/nest boxes. There will be a plastic baby gate blocking it so the litter and birds won't escape. Am I right to have it swing out? 7. The nest box will have outside access--one long door, about 3' wide. First, how should we latch it shut, and second, should the door lift up or drop down to open? I can think of pros and cons to both, so any experience-based answers will help. That's all I can think of for now. Thanks so much for your feedback. I'm so new at this but so excited, it's all I think about!!!
