When my corn snakes were just babies, I had them sexed by a local reptile shop. While the guy is sexing the snakes, he was talking to someone else. During their conversation he states "yea, sometimes I don't know the answer, so I just make stuff up." I'm thinking....great. This guy is sexing my snakes and for all I know, he's just making it up. So I had plans to bring them back to be sexed on a day he wasn't working. Fastforward over a year and I finally have a chance to bring them in. Now the guy before was popping them and gave me the sexes of...

Anery - Female
Amel - Female
Snow - Male
Normal - Female

I took them back and had a different person sex them (he no longer works there) and she probed. Her results were...

Anery - Female
Amel - Male
Snow - Female
Normal - Male

I plan on getting my own probe set at the next reptile show if they have them available and sex these guys myself. What is the standard number of scales when probing that indicate a male or female? How reliable is this? I've used tail tapering to sex corn snakes before. It was later confirmed with probing. An example is my adult snow corn. When I bought her the guy said she was too small to sex and to come back later. Several months later I had her popped and probed and he said its possible she was a female but he couldn't be certain because she went to a certain number of scales (for the life of me I can't remember). He said to watch her tail and see how it tapers. As she grew her tail tapered very quickly so she was guessed to be female. Later she was probed again and the man confirmed she was female. Again, I do not know how many scales but I remember that he stated when she was younger and was probed, it went in to the length that is directly at the upper range for females and lower range for males so he couldn't be certain.
