I'm building a 4'x8'x4' coop inside a 14'x20'x7' covered pen - should be plenty of space for our current flock of 4 chicks. Hopefully my wife can be convinced to add 2 more. For the ROOST area, I'm planning the 45 degree ladder style with 2 roosts, 36" each. The 2 roosts will be 12" apart and 18" from each end, horizontally. The question I have is: Is it better to use round tree branches for the roosts, or using 2x2? If using 2x2, should I position them to be horizontally flat or just leave at 45 degree (easier to do)? I remember reading somewhere that 45 degree roost might hurt my their feet. Also, the roosts will be 15" and 27" off the floor. Is that too low? I don't have space to set them much higher. For the COOP ENTRANCE, it's going to be 12"x12" square, about 2 ft off the ground. 2 questions: Do I need to set up a ladder from ground to entrance? And do I need to provide a door to close this entrance? The 2 reasons I can think of for having a door: (1) protect from predators, and (2) keep warm during winter. But I already have an enclosed pen around it, and California weather doesn't get below freezing. Any other reason to close the entrance? I'm planning to leave the waterer outside the coop so my girls need to be able to get in and out. Finally, I plan to set the NEST 2 ft above the floor. Is that too high? I don't have space to set a ladder inside the coop. Should I set it 1 ft off the floor instead? I haven't own chickens before, so I can't imagine a pregnant girl jumping 2 times her height to give birth. Please share your wisdom. I have to remember taking pictures along the way & post when I'm done. THANK YOU!
