I just recently got a four month old female ball python. Overall she seems healthy, I've only fed her once since I got her about a week ago and it took some time for her to settle in, but she ate well. I have noticed, which I think has been there since the day I received her, she has a very small spot on her head where only a few scales a missing. It's not big at all - just a couple scales.

This is my first snake, so I am new to the whole idea, but should this be something I should worry about or only if it increases in size?

Thanks in advance.
