Re: unfertilized follicles
How old/large is your male? Are you certain your male is a male? If your female is getting big and hasn't ovulated yet, I would continue trying to pair the male with her, especially on rainy days as the low pressure systems seems to stimulate activity. Worse case scenario is she absorbs the follicles and nothing happens. Best case is they lock and she lays. Best of luck whatever you decide.
Re: unfertilized follicles
yea he is a 2010 proven male... i honestly think that I had been feeding him too much and maybe he is a little lazy...after reading about males being lazy sometimes, I have cut him back to only small rats...that could also be a possible reason he is not breeding b/c I didn't feed him as much last fall as I had the previous year when he did successfully breed, as I was trying to let him lose a little weight
I will try the trick when the barometric pressure changes and see if that does anything.
