I bought a 'playhouse' from the local high school to use as a coop for our 3 Welsummers. It is 4' x7' outside dimension, divided into a 'porch' area and an area which a little girl would use as a house, divided by a half-wall. My question is this: the inside dimensions of the 'house' side are 3.5' x3.5', which I figure out to be 12.25'- big enough for 3 hens, right? So, should I completely divide the playhouse and use one part for the coop proper and the other side as an area for the cans which will hold the food, grit, etc and assorted shovels, etc, or should I remove the half-wall and let the girls have the whole thing for themselves?
