I have 9 hens, with 4 nesting boxes. Two of my hens have been in 2 of the nests 24/7, presumably brooding. There's always plenty of accessible food and water available for all the hens. But unless the two brooding hens are sneaking out of their nests at night to feed and drink, they are going without food and water. Is this normal, or will they just resume eating when they get hungry enough. They've been brooding for at least 2 weeks.
