I have 7 Pekin Bantam chickens that will mvoe in in about 3-5 weeks! The coop is going to have one closed part witch is about 125cm x 125cm and a small outer part which is about 60-70cm wide and 125cm deep. 1st Picture: Im making 3 nest boxes on the secound floor, the depth is 35cm and 40cm wide. Is it enough? I havent really found a way to moun the OSB-boards standing up like that, any ideas? I need a way for the chickens to get up there, i didnt think this through very well, maybe i will just make some stairs from the outside part of the coop. 2nd Picture: Theres going to be a wall mounted on the outside of those 2x4's. My plan is to have roosting bars on the inside along that wall, maybe 2 different hights, maybe up to the secound floor, which is my i dont have the nesting boxes floor covering the whole 2nd floor. What do you guys use as roosting bars, and at what hight? Please look at these pictures and tell me if something looks wrong or off! Im very new to this...Thanks!
