A few shots of my 19 day olds. The rooster is a Speckled Sussex and I show what I am guessing the mamas are under the photos. This is juvenile plumage. From Henck's calculator I expect all the adult Buff Orpington and the adult female Delaware offspring to be pretty much solid red with the solid Columbian markings when they mature since that speckling is supposed to be a recessive gene, but expect the Delaware males to be off-white with black barred tails and maybe necks since the Delaware have the sex linked barred gene as well as the silver gene. It will be interesting to see how they actually turn out.

The ones that were yellow at hatch had different coloring, some a bit redder than others. I think the redder ones are red sex link female and the yellower ones were the sex link males. I can't tell a whole lot of difference in the yellow chicks now, but at hatch the difference was more pronounced. In the photo below, the two chicks to the right are now colored about the same. They were one day old in this photo.
