Leopard Gecko hatchling!

Question
I received a female leo about 2 1/2 months ago she is around 2 years old. She has a setup of a 20 gallon long tile flooring a humid hide, hot hide and a cool hide. I noticed she was restless when I got her and would move everything in her tank around the first week I had her. I had NO idea she was gravid since she is my first leo ever. I didn't notice any eggs or anything. Then today I went into the room to do some cleaning of the tank and picked up the hot hide and there were 5 hatchlings in it! All of them are very much alive and have been moved to prevent them from getting eaten.

I was told it was impossible to hatch leo eggs inside of their tank ever. So I guess what I am asking is do you have any idea how these 5 hatched inside her tank?  

Answer
Hello Stryker,

Wow, that is quite surprising.  Were the eggs laid on the warm side of the tank?  If they were warm enough, it definitely contributed to them hatching.  
What are you going to do with them now?  
Poor girl, she obviously just had to get them laid.  
I bet that they are so cute, too.
