RE: [gecko]Rhacodactylus Eggs

[Rick Gale]

One of the easiest ways to tell is to candle the eggs.  I had a lot of 
trouble finding out just how to do that when I first started, so I'll give 
you a little info.  I use a mini-Maglite flashlight, narrow the beam to a 
point, and put it up against the egg so that the egg blocks the opening 
where the light comes out.  You want to do this in a dark room.  Fertilized 
eggs will candle a pinkish color, and you will usually be able to see little 
blood vessels.  This is even more reliable the older the eggs get. You'll 
also see a larger and larger dark spot inside that is the developing embryo.

In my experience, infertile eggs candle a yellow color, without the telltale 
pink glow and blood vessels of a fertile egg.  HOWEVER, I've been told that 
you should NEVER throw out the eggs until they mold, explode, or otherwise 
demonstrate very clearly that they are infertile.  Until then, there's 
always that off chance that it's just a slow developer.

Hope this helps!
Rick

A newbie question here.... How can you tell the fertilized from the
unfertilized eggs?
Thanks,

Jim
