I am expecting my day old's probably tomorrow. I have a clear large tote set up with wood chips covered with paper towel, a feeder, 2 water's and 26 chicks coming. I have a heat lamp that is adjustable for height and a hardware cloth cover. Is my tote big enough for the little ones for a couple of weeks? Then They will move to a larger brooder, and eventually work their way to freedom (to their own little coop with their own runs covered for predator protection). Also when can I introduce scratch to the wee ones? My tote size is 28" long 18" wide 13" deep.
