I began building a chicken coop last weekend for my Cornish X that I am getting ready to order. The dimensions are 8X8X3 tall and half is covered. After looking at it I thought maybe it was going to be a bit small for 25 birds and decided it would work better for 8-10 layers. My question is this. Since it is only 3 feet tall is this too short to allow for roosting space? Will the nests be too close to the ground? I decided that I would do a more simple space for the Cornish X and fence an area off near my garden, cover it with avary netting and build a simple lean-to for shelter. Have I over thought this process too much?
