The reason I am asking all the questions is I am considering stocking a few adult single sex CNBG in my pond with my Northern BG the spring of 2017. That would give them all summer to find a mate and cross with the Northern BG. I could, hopefully, see if a CNBG x Northern BG cross and/or pure CNBG could survive one of our northern winters and, if they do, how they perform.
