I've been setting eggs from my standard sized hens under the broody bantams in order to get some new mixed-breed laying pullets and eating roos. But the ones I want the most to hatch haven't! I have a nice Red Sex-Link who lays big brown eggs. In Jan I got 2 of her chicks, hatched in the incubator of our poultry club. The pullet is a nice layer now, looking like her mom, and the roo was a big genial guy. But so far, all 3 broody hens left these eggs unhatched. And when I checked them, there were fully developed chicks inside. What should I do next time I get a broody hen? Collect just this hen's eggs to put under her? I'm thinking they need more time for incubation, and the broodies have been getting off them too early, after the other chicks have hatched. Please tell me what you think.
