I spoke with a vendor at a reptile show yesterday about the fact that one of my 8 hatchlings is not eating. She said the problem is that I have so few. I gave her a confused look and she went on to explain that when you have lots of babies every year like she does, you quit worrying about the few that don't feed right away. She said she had a few June hatchlings that didn't eat until August.
So, I am trying not to worry about my non-eater. She is still very active, and hopefully will eventually eat. Hopefully yours will too.
There is lots of good advice on these forums to read and re-read.
This is my first hatchling ever, from back in 2004.
