I'm going to build a tractor coop for 3RIR and 3BR. All hens. I'm only looking to raise hens for eggs at this time. However, in about a year, I'm going to expand my flock with a rooster and hatch my girls' eggs. Considering this, how many boxes should I make? What is the proper placement of the nesting boxes and roosts inside a 3'X4' coop. Should the nests be close to the floor for future chicks easy access? How would I feed/water chicks living in the coop? Any danger to chicks from other chickens? Where is the best placement for the roost? Will I have to have a special roost for chicks when they come?How soon before they can roost with the rest of the flock? Will a deep layer method floor covering affect the chicks?
