Just wondering if anyone else has seen this before:
Link here is to one of my Autumn coated girls.
She has had the same partner since birth(Rory) and they have produced 7 nests in their time together.

But......if you look at the nest details you will notice something odd......they are all Male :|

Has anybody else out there had a pair that has produced only one gender and if so, do you have any theories on why this has happened..
