We have 4 girls that we hatched here. It started with a Rhode Island Red Roo and 6 Barred Rock Hens that we bred together to get Black Sex Links. When the Sex Links were of laying age we bred them with a Leghorn Roo. With the Barred Rock being the dominate gene in Sex Links and mixing with the Leghorn the chicks came out pure white and once they feathered out look just like White Rocks. So we kept 4 girls and raised them up. They started laying at 18 weeks and now all 4 of them are on an egg laying spree that has lasted for 43 days. We do not give them hormones or anything. They eat Purina Layena feed and are given popped pop corn once a day as a treat. And through heat and storms and such, each one has layed an egg every day without fail. They are free ranged and extremely spoiled. We are now hatching a second generation from the 4 girls who were bred with a white roo that is one of their hatch mates. We are interested to see if they will also start laying that early and that often. And yes they did turn out all white for a second generation.
