Broody hen hatched 4 of 7 eggs yesterday9 /21. The chicks are peeking out from under broody 11×11 nesting box. Do I need to worry about them getting out for food and water?? I have food and water right out side box but no chicks have come out of box yet. Should I just let broody take care of business, she seems dedicated? Still pretty tame for being a mamma.
