Ok Tony, let me throw another variable at you. We obviously have a longer "growing/feeding season". Do 1.5# BG live longer, and take longer to get there, due to a slower metabolism during the longer winters you have? If my CNBG live an average of 5 years, I'd be curious to know if your BG live an average of 6 or 7 years, or if the colder water is a nonissue.
