I am just about finished with my coup. My Rhode Island Reds are about 4 1/2 weeks old. I'm planning on putting them out with probably a heat light at night, I think we're looking at high 50's at night this week. My question is my poop board is 21" from the floor, with the roost 31" from the floor, is this too high for them at this age? Should I put a temporary roost at a lower level for awhile? Nesting boxes are about 18" off floor, which I am planning on blocking off until its comes closer to laying time. One other question, the roost is 12" from the ceiling, is this too close to the ceiling when they are full grown?
