I have 3 different chicken breeds - Andalusian(1 blue, 1 black, 1 splash), 2 Speckled Sussex, and 2 Light Brahmas. I have read that the Brahmas are very likely to go broody and that SS often go broody, too. When I do get a broody hen, I want to hatch out eggs under her. I know someone who has Swedish Flower Hens(including a roo, so the eggs are fertile) and says I can have eggs from them. But how many eggs can go under a broody, and can a really fat breed(like my Brahmas, 5 months old and 4.5 pounds and could still almost double in size) take care of more eggs than a smaller breed, such as the Andalusians?
