Im sure that has to be hard. I cant even imagine how three turtles could grow in one egg! I cant tell, were the other two deformed? the one appears to look normal.
This is amazing, I've seen images of twins often but only once saw triplets and They survived initially but one by one passed within a few months. I wonder if theres just not enough nutrients in there to successfully start off so many youngin's together? Its amazing that they were all perfectly formed though. And i'm sorry about the losses, I assume the others were all successful though?
Ah, what a shame that they didn't make it. I'm not surprised, though. This is a VERY unusual occurrence. I'm glad you thought to take a picture of them.
