As my user name suggests.. I am incredibly lost and confused and more than a little hurt. I would really like some answers as to what could have happened to my eggs last year. Out of the 9 eggs...None of them hatched. Not one a single one. This will be my 3rd year breeding my ball pythons and while the first year was a little rocky...this last year was completely heart breaking.

I would like to ask all you fine folks what I did wrong? What could I be doing better and so on and so forth because I don't want this happening again if I can help it. I realize that things sometimes just go wrong without explanation but I'm hoping that I can grow from this experience.

Last year I was able to successfully breed my female spider (1800g) to my male Pastel (1500g) and my spider gave me 6 beautiful eggs. I also successfully bred the same Pastel Male to my Pastel Female (1500g) and she gave me 2 beautiful eggs, one not so beautiful egg (misshapen and small) and one very obvious slug. I candled them all and the viable ones all had large strong veins.

I already had their incubator set up to my desired temp of 87 degrees. I had their boxes set up as well. 6qt plastic shoe tub filled with moist perlite. I placed plastic egg crate on top of the perlite so the eggs were barely touching it and I covered it with plastic wrap to seal the moisture in. No turning of the eggs or anything. I made sure they were in the exact same position as I found them.

My incubator is made out of an old wine mini fridge with a glass front so I can see inside without continuously opening the door. We gutted it and put in parts of an old incubator inside. I used two probes on the top and bottom of the incubator to make sure that the temps were consistent at 87 degrees. I also had a small computer fan blowing to circulate the heat.

I placed them in the incubator and waited. I'd check on them daily through the window to make sure the temps held and from what I could tell...they were holding steady. I checked to make sure they weren't rotting or drying out. Not enough condensation built up to drip on them either. Every week I'd lift up the seal and press to let fresh air in. Everything was fine until day 25. One of the eggs was turning a sickly green colors. I took them out of the incubator into a temperature controlled room and candled them all again. All of the veins were still strong except for the one that was turning sour. No veins showed at all. Unfortunately it was attached to 3 other eggs and wouldn't budge. For fear of tearing a perfectly good egg I left it there for 10 more days until it deteriorated so much that I could finally pluck it off. During that waiting period two other eggs died that weren't attached to the rotting egg. They weren't attached to any other egg so I removed them too. I put them all back, waited and waited with no other signs of trouble. I took off the seal and wrap at day 52.

Day 58 came and I panicked and decided cut the eggs. They all looked fully formed but two of them weren't moving at all. The other four would twitch or show some signs of life. No veins were knicked. I was getting more and more worried.

After that day all hell broke loose. Not one of them was absorbing their yolk. Not one of them was coming out of their egg. I waited until day 65 and pulled the box out to check the eggs again. The two that weren't moving were definitely dead and another two others had joined them. All of them still had yolk sacks attached. Some of them were wrapped in their cords. That left me two eggs that still looked like they could make it. Day 68 and another one of the babies had wrapped itself up in its cord. Day 75 and the only egg left was the misshapen one. He'd tried to make it till the end and even partially escaped... but his yolk was still attached and stuck in the egg. And you guessed it...he didn't make it either.

If you read this till the end I thank you. It was very long and dull I'm sure but I wanted to make sure I didn't leave anything out.

Questions if I may... Would moving the eggs from their incubator to a temp controlled room be enough of a drop in temp to kill them? Is moving the box at all ill advised even to just check on them? They didn't role at all.

What are some reasons that a baby ball python would be fully formed and not come out of his egg? What are some reasons that they wouldn't absorb their yolk?

Also, I hear a lot of people adjust their temperatures for their breeding ball pythons before breeding season to simulate the winter season in Africa? Which gets their Ball Pythons in the mood and to know that breeding season is on the way. Which helps in aiding a female to produce follicles?

If I didn't do that last year could that be one of the reasons none of the babies were strong enough to make it?

Thank you so much for your time. I greatly appreciate it.
