Wow! Thanks, that is a pretty detailed description. It doesn't sound like a cross I will make on purpose.Males will look like a barred dark brahma with some salmon red on the shoulders and straw hackles ( salmon develops as the bird ages). The barring will be poor and zonal ( breast, tail and mid-wings), The amount of red and straw color can vary from none to a diluted salmon phenotype. The barring in the hackles will dilute the hackle color- barring will be very poor. It all depends on the amount of hackle black the males will express if the barring is distinct or blurry.
The females will show indistinct penciling- like a poorly penciled dark brahma.
Body size for male and female should be between CCL and brahma, Combs will be a strange looking- a single comb with a pea comb on top. Females will have a small weird looking comb, Blue to green egg layers. Most likely green egg layers.
This all depends upon if the chickens are purebred for the genes they should carry. I am not saying your birds are hybrids- birds even shows birds do not always carry the same genes.
