They have quail waterers at Runnings... don’t know about TSC. Look on Amazon. I’ll bet you can get them there. They’re like the mason jar chick waterers, but with a much narrower trough.
Regarding why the colors don’t breed true and why they don’t just tell you which two birds to cross to get the colors you want...
I don’t know, but I suspect the sellers have done a lot of experimenting to figure out how to produce this or that color in a chick. They may, like the Cornish Cross chickens, be the offspring of hybrid parents. If this is the case, they’ll be complicated and time-consuming to breed and also the result of a lot of exacting research which the researchers probably don’t want to give away gratis to the world at large. They may license their methods to producers for a price, but would understandably be hesitant to toss out their ability to profit from their hard work by sharing all they’ve worked for, for nothing.
I’m just guessing—positing a possible answer to the question. I’m probably way off, but I’m betting it’s at least something to do with protection of intellectual property rights.
