Moreover, do chickens sleep in their nesting boxes?
The first, and main, reason why chickens sleep in nesting boxes is the nest box is higher than the roost. Chickens will try to roost for the night at the highest place possible in the coop. If your nest box is higher than your roost bars, your chickens will try to claim it as a sleeping spot.
Both the male chickens (roosters) and female chickens (hens) have an orifice known as a cloaca that when brought together, transfer sperm to the hen’s reproductive tract. An interesting fact about hens: they can eject the sperm of a rooster after mating.
When the springtime rolls around, the hens’ hormones go into top gear. In nature, this means the associated behaviors of finding a suitable mate, nest making, laying, and sitting on her eggs until they hatch. In many hen breeds, this instinct has almost been bred out of them, so they don’t waste time and energy in being broody.
