I just built me a 9x6 coop and i still have to build the coop i need it small so i can more it when needed i built the pen where i can put wheels on it when i needed it moved but now i gotta come up with an ideal how to build the neat box and roost its gotta be detachable so i can move that separately when needed. I only have 3 sheets of plywood left and i was thinging about making a 2x2x8 square box type but dont know how big i should make the nest boxes i have a total of 6 bantam hens so i need at least 6 boxes in each compartment "oh by the way the carpartments are (36 inches long 24 inches wide by 2 feet tall) Any ideals???? and should i put the roost inside the coop or outside since its so hot here?
