Admittedly not dwarf, but fascinating none-the-less. |

If she only produced one good egg out of the clutch, then you need to make nesting better for next time. You may have been lucky and this egg may have survived but it sounds to me that she is holding on to them too long because nesting area is not quite suitable or either you did not quite catch the ovulation timing with fertilization and the others remained unfertile. Were all the eggs laid around the same time or were they scattered over several hours? |

I know what the problem was. There is an area of deep sand/soil mix which she was digging furiously in. However, I realised, a little too late, that it wasn't damp enough to hold a burrow. She laid a couple separately at different times, but the rest were all laid together inside a small box. (It was not meant to be a nest box, so was far too small for her to properly lay in.
I am almost certain that this egg will not be valid, despite looking good. But, never mind, at least I know now for next time.

That`s how we learn in this hobby, through trial and error. Good luck and fingers crossed for you for next time.
I love the picture where the animal is approaching the camera with tongue on display. Cracking shot. _________________ YSBRYDOLI POBL, GWELLA LLEOEDD

Something that usually gets overlooked for nest sites is temperature. My monitors' nesting area has a thermostatically controlled heat source and it works a treat every time. She's laid as early as 22 days after first mating, which is the shortest time I've heard of for a lace monitor and I think it comes down to confidence with the nest site.
Sean, you can time mating with vitellogenesis, but we have no control over timing ovulation. Ovulation occurs some time after mating. |

What I mean is the female still ovulates even when there is no copulation or no presence of a male. For example I had a female argus that produced eggs 4 - 5 times a year for about 2 years before I got hold of a male, obviously the eggs were infertile but if I would have had a male and timed it right then they may have been fertile providing the male was good. Yes I agree temperature is important. |

Sorry, I was just being technical. I know what you were getting at and I am aware that females will produce eggs in the absence of the male, but I was referring to this statement which you made:
Sean wrote: | ...or either you did not quite catch the ovulation timing with fertilization and the others remained unfertile. |
My point is that it isn't the ovulation you have to get the timing right with, it's the vitellogenesis ('cycling'). If you don't pair them up when the female has yolked her ova and is receptive, you may get infertile eggs. By the time the female actually ovulates, it's WAY too late and you've well and truly missed the boat. My female ovulates around 16 days after she and the male have started mating. Mating usually stretches out to ten days max, so that's almost a week after she's stopped being receptive. |
