Ok, I tried sexing them. I thought four were boys and six were girls. When I picked them out of the original 19 I tried to pick more of the smaller ones than bigger ones.
I found penises on only 3 of them. One either fooled me or is hiding it. And of course I could be wrong on the ones I thought were girls. I banded them all so I can keep track and see how right I was. So here goes.
These are the ones that are boys.
Here is the one that possibly fooled me.
These are the ones I think are girls. The one that possibly fooled me is the one in the very front.
I really looked for a bit and couldn't find any evidence of this little chocolate being a boy.
This is a good opportunity to see how well I really am at vent sexing.
