I have a female with a proven male since mid January she's still not pregnant at least I don't think she is. My concern is that her tail base is so thick like the end of a big asparagus can this be a problem of her not getting pregnant?
No, some have extremely thick tails, some have thin ones. I've never noticed a correspondence. I'd give her a few more months, douche/swab her and move her to a more productive male.
I have never in my life heard of tail bases having anything to do with breeding at all...and only in breeding since mid-january...That is NOTHING in breeding time. It can take a while for them to breed sometimes. It has only been 7 months
My thick tailed girls seem to be the biggest girls around here, and large girls are sometimes slower. I agree with Kristie: since mid-January is nothing! . I start to tear my hair out at a year with the same male & no kits...
That is not much time. I put my **** beige girl in breeding last January (2010) and only now (July 2011) did she have babies. She was also with a proven male. Same with Spaz... took her two years to get finally pregnant.
I've never heard of tail base having anything to do with reproductive success or lack thereof.
