My corn snake just had a shed about a hour ago, and it was a perfect shed as usual. I have two corn snake books and one says you can count the subcaudal scales to determine the sex of the corn snake. They say that females have 59-70, while males have 70-80. My girlfriend and I both counted and we didn't share our answer until both had counted so we wouldn't be influenced by each others answers. We both got 65..... My question would be is this method effective, or has anyone used this? The only problem I see is that unless this is a full proof method then, 66 is very close to 70. Any help.
