Hi everyone, I am planning to get my first chickens soon, and am working on how to design the coop and run. I have learned so much about the deep litter method on this site and will use it in my new run. My question is how to design the run to best accommodate it. I will have a coop with a roofed walk-in run attached. My question is how to avoid having the litter spill out when I open the run doors. The site for the new coop and run is currently a 7' by 18' raised bed framed by 2x12's. Should I have the bottom of the run door set above the 2x12 and dig out the soil that is currently in the frame to accommodate the coop and run? Or would you start at the current level of the soil and build up from there? Also, in your opinion, how deep should I allow for the deep litter method. My current plan is for 3 chickens in a 5'by5' run with a 60 sq ft run attached. When those three hens slow down with the egg laying I would like to get three more chicks, but don't plan on ever having more than a flock of six total. I am hoping to allow them to free-range when I am outside during the day and can keep an eye on them. Thank you for any suggestions you have for me.
