The only one that I can see well enough to sex, is number 2. And sorry to say, that one's a boy too. But, there's some good news. The female parts sprout slower and are smaller, so they're harder to see that the male 'balls'.LOL So, it's likely that you have a few girls in there. Take some more pics damnit, this is fun. LOL j/k Maybe this will help you sex them yourself.....the female parts come to a point, and are sorta coneshaped. They'll be in the same places that those little 'balls' are, so you should be able to pick them out of you look closely. It's tough though, if you haven't looked at a bunch of them before, so don't get discouraged if you can't. Maybe somebody has a camera that you could borrow?
