Sexing young stock

[Pikku]

Okay, my first litter is hitting six weeks tomorrow and I am trying to get the hang of sexing them. I can easily see the difference in my adult stock. It's these babies who are confusing me!!! If I put a little pressure this one looks like a doe, but if I put more pressure it looks like a buck. Not sure the correct pressure to get an accurate sight. I will be posting the rest of the litter as I take their pictures! This is the one I am keeping so I am most curious about. My best guess is boy?

Buck

A doe will never invert to a tube no matter how much pressure

Awesome! Good to know. That litter is all males then I think. That was what was confusing me...They all looked the same! Thanks
