I was doing a little research on the Delaware breed and came across the musings of a fellow who was part of the breed formation. After going over his comments about ten times, Im reminded of another one of those bewildering moments I suspect everyone can relate to. GEICO, the insurance company, has a series of commercials featuring a caveman and the slogan, "GEICO.com - so easy even a caveman can do it." In one of these commercials the spokesman caveman and a psychiatrist are sharing a split-screen TV interview with an announcer. Do you know the ad I mean? The commercial opens with the psychiatrist blathering some psycho-babble crap, like: Well, it is cleeeeearly evident that the socio-manifestations currently exhibited are symptoms of a deep neurosis within the inner cortex, leading to a general malaise and relationship discomfiture. The announcer then says, Any comments? to which the caveman replies, after a moment of pregnant silence... Yeah, I have a comment WHAT?! Well, call ME the caveman, since thats how I felt after reading the following about the Delware breed creation: In those days the popular broiler cross was Barred Plymouth Rock x New Hampshire. If the barred broiler males were inadvertently mated with New Hampshires, the progeny would be heterozygous for dominant black extension. A heterozygous male mated to a New Hampshire might be the progenitor of the silver (but barred) sports we occasionally saw. All the other sports were inferior. Of course the sports had to be silver or we would have had a barred red. We knew nothing about the inheritance of Colombian but in hindsight, two crosses to New Hampshire might give a few homozygous Colombian (CoCo) individuals. In hindsight he had big problems because the silver in the Colombian pattern is dominant to red. So his birds needed to be progeny tested to identify the purebreeding silvers. So, can anybody explain this in a way that even a caveman can understand it?
