It's shell has been like this from the first day I got my baby I'm not sure if it is normal or if it is something that I need to have checked? It is growing and acts fine. It was the size of a half dollar and weighed 21.7 grams the day I got it and weighs 400.4 grams now.
Okay that eases my mind I was worried that something was wrong. It's eating, drinking, and active but this is the first time I've seen that line turn pink.
