Being so far away I'm sure I was a little later in getting my copy of the MCBA mag.
I see that topics haven't changed much sense 1966.
Reading the ranch reports about the effects of lighting was very interesting.
I am going to try some of those experiments myself.
After reading I had to check my files.
For the last 2 years I checked, I got females kits born from Jan. - June, and males from then to years end.
They do have a small SE facing window that I have never covered, plus daylight florescent tubes that are on from at least 9:30 pm to 3am.Yes we are nocturnal as well.
Then they have darkness until the sun comes up. So mine get very little total darkness.
Have any others noticed season trends in the sexes of your kits?
