I've read that when you crossed native chickens (philipines, caribbean, hawaian, egyptian) with US layer chickens you will get hardy layers adapted to the climate like the local chickens. In your opinion what would work better: native hen x leghorn rooster? leghorn hen x native rooster? Or is it the same? I have leghorn hens and I could get a native rooster easily. How long before I get fertilized eggs, once I introduce the native rooster? One more question: If I feed native chickens layer feed will they lay better and bigger eggs?
