Croygenic processing has been around for number of years in NASCAR but it is starting to be used in off road racing as well as many other forms of racing, too. Caven says he uses a ring pack that is less than 3 mm for the CORR engine, and that the oil ring is really just there for insurance.
Hybrids are the earliest birds to start laying, starting about 1 month earlier than non-hybrids. Non-hybrids, which include our rare and heritage breeds, typically begin laying about one month later than hybrids. Most of the egg laying hybrids start laying at 4 to 5 months of age. These include Pearl White Leghorns, Black Stars, and Red Stars. Hybrid egg layers are bred by crossing two different lines or breeds. They are known for their excellent productivity and high feed conversion ratio.
Leghorns rarely exhibit broodiness and are thus well suited for uninterrupted egg laying. The Leghorn is a light breed that matures quickly and is not considered a viable meat producer. Leghorns are active and efficient foragers and are one of the best for free range chickens that can avoid predators.
