Why is that? Is it because they have to lay a clutch of 100 eggs or something to get them to sit? Why wouldn't they want to sit after a half dozen eggs or so? Can you force em to sit? What if I had a flock of 12 hens and one roo and no electricity...how would my flock continue without an incubator? Set the eggs in an aluminum egg carton in the sunlight all dang day? Has anyone had a RIR go broody? learning this kind of ruined my plans for my RIR's to rule the galaxy and all. Boooooo.
