I REALLY need a new coop. I've got my new layer chicks in the brooder already but I also have Bantam Cochins, no more than 10 though. I will have about 12 laying hens after I pick out the roos & non-keepers. I want ONE coop, but seperated into two on the interior, make sense? How big should the main building be to give enough space for each flock inside their seperate coops? Here's a quick sketch of what I think would best fit my needs and be good for the chickens too. just not sure how big it needs to be. "Interior view" from above The runs would be covered with (probably) metal roofing to keep them dry & fully fenced with chicken wire. I am not sure how the inside should be done.. I was thinking the lower 2-3' of the interior walls(walkway) should be plywood & then chicken wire to the top. just to keep the walkway cleaner & roos in opposite pens from stressing out at eachother through wire. Not sure about nesting box & roost placement yet either. or even if I will have room for feed storage space! Welcome all input!
