Click on the thumbnail to see the most current version of my coop plan. I have an 12'Lx10'W shed I plan to section off into a 5x10 coop and a 7x10 storage shed. This will be our first coop and we're looking to house between 5 and 20 birds, probably starting w/ about 12. So I'm looking for any suggestions from experienced chicken folk on how to make this the best possible design. I'm sure I came to the right place. The two blue circles are a feeder and waterer, both of which could be moved into the run on a temporary or semi-permanent basis. Current plan is to cover the existing wood floor with linoleum and use the deep litter method. The shed is built in to our garden fence perimeter (garden to the right) and we can therefore let the future flock straight out into the garden to till and forage before planting or after the harvest is in. I know they can eat the garden, so we'll be careful to exclude them during the growing season. The run will be L shaped and wrap around what are the top and left sides of the shed in the plan. Big concerns: 1) We currently get coons and groundhogs under our shed. They can't get through to the garden because of concrete and fence buried on the garden side of the shed. Do I need to do a similar treatment all around the edge of the coop, even if the fenced run will cover the other side and back? Or am I ok just doing the only remaining exterior side (bottom edge of the shed in the plan)? Should I put some kind of wire underneath the linoleum before laying it as additional protection? 2) Ventillation. The shed currently has no ventillation and gets stifling in the summer. I'm in Cleveland, OH and we get 90+ degree heat in the humid summer and down below zero occasionally in the winter. Will two windows on the shed sides (one on the left, one on the right) and a screen door and gable vent on the remaining exterior side (top) be sufficient? I can only vent on three sides without modifying the storage side of the shed. If this will not be adequate, what additional ventillation is recommended? I do not want to modify the roof, which is already flat on top and not conducive to roof venting. I like this plan so far, especially because the layout drawing looks like a robot.
