ahhh. I'm so excited for my geckos to breed but its hard not knowing what to look for. Also, my female is larger than my male and she likes to play the man of the two. (Shes the one who likes to shake her tail) She tries to climb ontop of him and he just runs away. It's quite funny to watch actually. I think from what I have read if your egg has pink instead of yellow it means its fertile! Hopefully you get a baby!
