First time with broody hen. She sat on nest for 3 days without eggs and without coming off to eat or drink. I let her have 3 eggs to set and lift her off the nest each morning to eat, drink and poop. How long can she be off the nest and still keep the eggs viable? I always find her back on the nest later in the day. This morning I stuck around to see how long she would stay off. When I had to leave she had been off for an hour mainly dust bathing. I suspect an hour is too long for the eggs to survive. Thanks for all your experience here.
