The sussex to buff orpington would be a good cross to start with. The offspring from the first cross or F1 would be orange red because of the dark bown gene. Only hatch ten or so birds. Make sure the male sussex is a dark red bird. Or if you use females only use birds that are dark red.
Then cross a male offspring and female offspring with the best type- this time hatch 20 or more eggs. From this second hatch you should get a few black tailed red birds or red birds.
You can now back cross the black tailed red to the buff orpington to increase type. hatch 10 or so.
Pick the offspring from the back cross with the best type and cross them together- hatch 20 or more chicks- you should get a few black tailed red birds or red birds from the cross.
Continue to cross for best type and the least amount of black in the tail.
The mottling gene will show up from time to time- you can make speckled orpington also.
Be patient- black tailed red would be the easiest variety to produce. Red is more difficult because you have to through breeding remove the black from the tail.
You will have to pick a color standard and breed toward the color standard while also breeding for the orpington type.
