You won't get all those colors out of the first generation.
Blue slate is BBDdRR (black based, single dominant blue gene, no red) and Bourbon Red is bbddrr (bronze based, no blue, two recessive red genes). When crossed the first time, the offspring will either be BbddRr or BbDdRr.
The black base is dominant, so the first generation won't look like bronze based birds. So none of them will be bronze or bourbon red looking. They will all have only one recessive red gene, which also rules out bourbon red type birds. But single red genes do express themselves (golden narragansett is an example).
So the BbddRr birds will look like blacks with a single red gene. There is a name for this color, but I can never remember it. They are fine looking birds, though.
The BbDdRr will look like blue slates with a single red. While I am not sure exactly what this will look like, I would imagine something similar to
http://www.porterturkeys.com/blueredbronze.htm. These are bronze-based birds so there will likely be some difference, just not sure exactly what.
If you cross these offspring with each other, you can then get all kinds of stuff, including blacks and slates with no red, one red, or two red genes, standard bronze, red bronze, bourbon red, red slate, blue red bronze, and maybe a few more.
You generally have to bite the bullet a little to sell the crosses. If you raise them up and sell them as food, it won't matter. Even at $4/poult it can be hard to get rid of mixed birds in a small market.
