Hi I am after some help please. I have 1 pair of thick tailed gecko's and a colony of 4 (3f - 1m). 1 of the colony has laid an egg, very excited my first, now in the incubator for 1 week. And the girl from the pair has laid an egg 1 day later however still has what looks like an egg still inside her. Her tail is fairly thin but still eating like mad. Should I be concerned about this and how long will the other egg take to come out. Any help with this would be great as I don't want to loose her.
