I have a nest box about 3ft off the floor in the chicken coop. I decided to let one of Buff Orps go ahead a brood some of the eggs (she's actually brooding some Dark Cornish, and whatever else her fellow hens keep managing to slip in the side). I've never let any of my girls hatch out before, so this is a new experience. So....what happens when they hatch? Do they just drop 3ft from the next box down to the floor (dirt, w/ thick straw)? Will the fall kill/injure them? Do I move her to a ground level box (I'd had to build something)? Once hatched, will the rooster and other hens be OK or try to kill them?
