Turns out you were right about that cockerel, he is not paint.
Most paints do have a white tail, with or without black flecks(streaky spots) or maybe a half black tail feather. I'd have been very surprised to see a paint with mostly or all black tail. There are some with mostly or almost all black wing so I thought maybe a black tail was not so impossible..
Yeah silver columbian with barring is also called delaware.
That is exactly my goal, big/heavy but not overweight with lots of problems. I want them to be able to do all the normal chicken things with no problems and not needing special care in any way.
I also noticed the cornish x had nice personalities- very calm and completely non aggressive. They don't panic and so far the crosses are also showing this calm and tame personality. Very easy to raise in brooders and being in the pens all the time, not free range.
Yes have to use dominant white on black chickens, as dominant white mainly affects the black pigments and not very much effect on red/gold pigments. A good example of this is how the red sex links, some ISA browns are white on their necks and tails with a red body color.. that is the dominant white affecting the black tail and neck and leaving the red body mostly alone. So if you want paints, have to breed with black chickens, otherwise you end up with birds in that color pattern or something like red pyle- dominant white on a partridge/red duckwing.
by the way- It's supposed to hit 115-120F 43-48C this weekend.. I won't ever understand people who live in areas like this and refuse naked necks.
