Jason,
Your post got me to thinking why mine are only lasting -1 year. The majority of females I tend to kill off before they even get there because I find a new "cute" one I want to keep so I replace them so I don't count those guys in the count. I think I am going to start keeping a breeding card to see how long my females actually last instead of trying to keep track in my head since I have such poor concept of time
I thought it was a year, but I actually counted back and my favourite orange girl is actually going on 2 years instead of 1 year. However this morning she just dropped a litter of two
Maybe mine do last longer? I hope so!
How long do you find your males last? I'm a bit dissapointed in that I had to recently retire one of my males at only 1.5 years of age
My males don't have a big workload either of only 3 females per colony.
