Well it's your lucky day Rzrwyre
I tried to sex them this morning. On first count it looks like we have 3 boys and 8 girls, but I'm aware that they're only 3 days old so this will probably change.
Also, we have ears this morning!
The boys (so far)
And a close up of those little unfolding ears!
Their fur is really starting to come through now, I think you can see a few hairs sticking up on that last pic. They're so soft!
