My buff Orpington is really broody. I've got her on 13 eggs (today is day 7 of setting, about day 10 of her being broody). I have her caged with food and water very close to her nest, but she never moves. I get her up once a day and pop her out into the small yard (after first closing out the others, who are free-ranging), do my coop chores. She will eat a little bit of scratch (ignores the layer pellets) drink some water, drop a toxic dookie, and then wants to go back to her egg trance in about ten or fifteen minutes. She has lost a LOT of weight. I'm quite concerned about her well-being Is there something I should be feeding her during her brief excursions off the eggs that would provide more appropriate nutrition, and more calories?
