Come on i was just gona eat breakfast    So much for cheerios

Cheerios? That turned me off eggs personally...

The leaking egg could have been from undercalcification.  I have had that problem as well as the mother damaging the egg while laying in the past.  The shell lookes calcified from the second pic so my guess would have been damage after laying or if the embryo was already dead the egg was just breaking down via decay.

Come to think of it I have had all 3 of the scenarios i mentioned above happen this year.

I am not sure why your egg pipped unless the incubation temps were too hot or maybe you handled or moved the egg(s)? A hatch date of 5/21 really isn't that long of an incubation period. Normally they can hatch in 60 to 72 days and sometimes up to 100+ days. Unless the eggs cave in and dry out you should try to be patient. One of my best Red Harlequins hatched from a glorious blue fuzz ball back in 2006.

The best advice I can offer would be to make sure the female is getting enough calcium to produce healthy eggs. Also check the incubation temps are OK and be sure the substrate is slightly moist or damp NOT wet. Also, you can take notes on the parents (is this a first time mom by chance?).

Patience is a virture and good things will happen!

Cheers!

I'm not 100% sure if this is a first time mother, I got her earlier this year, but I think she is.  The substrate I think may have got to damp, I threw it out when I realized it had gotten too damp and started to mold.  It's hatchrite, so I'm not sure how it molded, but now there is substrate that I'm making sure isn't getting too wet.  I would have left it alone had it not been for the burst, it was a very small slit, but all that goo was sticking out and I thought they baby was trying to pip.  I don't think it's too hot, it's around 72-74 in the basement most days.  I think what made me paranoid was losing that other baby, it was fully developed, just never pipped and I thought maybe the shell was too hard or something else went wrong.

I'll check on her calcium, she's been the best of my 3 adult females for laying, the dal decided to lay a clutch, then skip a month, but now seems to be laying more consistantly, the other female was coming out of cooling and I hadn't paired her yet and she laid 2 eggs, I wasn't looking for eggs from her so they were flat as pancakes by the time I found them, not sure if they would have been viable anyway.  She then was paired with my male, laid 1 egg, then laid 2 eggs, 1 of which wasn't viable.  The red harlequin is the mom of this little baby and she has laid me 2 eggs each clutch since I paired her.  Hopefully bumping up her calcium will help and I'll keep an eye on the other egg, if that one leaks too should I just leave it or clean off the goo?

You can patch eggs with a small piece of paper towel or tea bag to stop the leaks, often that helps and the eggs will go to term. Sorry for your loss...I never ever cut eggs for this reason. I let Mother Nature decide. :(
