This is my first post, I am the newest of the new and look forward to being an active member of this forum. My dad is here in CA building an 8x10 coop for me and my 3 sons. He will build the back wall of the coop Saturday and that wall will contain the automated door for chickens to access the run. Dad is asking me what kind of a door am I planning. Will it go up and down or swing in and out. Please help? What door do you recommend? How can I get installation instructions quick? I have a fax. Who are the recommended sources? If dad frames a 15 x15 opening between studs in back wall of coop will this suffice? My friend is giving me (10) Americana 6-week old pullets New Years eve. We will have 6 external nesting boxes as flock may increase over time. We are also building an A-frame run that is 10x16. This run will be lagged into 4x6 foundation timbers. My boys and their friends are doing the site prep on this today. Thanks in advance for your tips and suggestions. HAPPY HOLIDAYS TO ALL from Los Gatos CA.
