So we bought the chicks before I designed and built the coop (we have 5 outta the 3 we are "supposed to have, but they have all made it 3 weeks.) My original plan was to build a small 4x4 with nesting boxes attached on the outside then build an enclosed run to keep critters out. We have raccons, mean cats, hawks once and awhile. I use to live on a farm and I had about 80 chickens then, its alot easier to throw up some ugly pallet made coop in the country but I have to keep my yard/garden looking decent. 16sqft isn't going to be enough for 5 chickens, or could i get away with it? I was going to build a tractor style coop but have no reason to spread poop all over the place, I'll save that for the compost bin.
