I've crossed the Delawares with New Hampshires and the chicks are looking just like Delawares and they are the same size as the RIR chick 3 days older. There are some of us who are trying to breed SOP birds that grow fast and lay lots of eggs I don't know that I will show but by breeding to the standard you get a better bird and by picking faster feathering birds you get more eggs and meat
