Well, I finally thought I had this new extra large Brinsea OvaEasy down. That is, until last night when I candled my newest batch of 24 eggs at Day 7. They were all fertile (yay!), every single one of them but...they had a mysterious splotchy, clear spot on all of them. I had never seen this before. It wasn't a blood ring, I know what that looks like. So what was it?
Of course I set out putting in every google search I could find. Contaminated eggs? I doubt it. I sanitize the incubator thoroughly after each hatch. Temp to high? Couldn't be. Last hatch and the previous 6 before that did fine. Humidity too high in early development? Possibly. Last hatch was a day late but.... No blood ring to show death.
After an hour of google searches on incubation failure it hit me...I may be the cause of this. In the last 5 hatches since I got the OvaEasy I hated how the eggs rolled in their tray during turning. I was worried they would bump and possibly crack, scramble the embryo, or roll out. So...for this particular tray I locked them in. Thought it would be fine. What I did as cause them to not turn properly causing the yolk to basically stick to the membrane. Great....
I am leaving the eggs (now properly restored to their rolling ways) in for a few more days in hopes that it's not too late since I didn't see a blood ring. If development hasn't progressed then I will pull them.
On a slightly brighter note their is 1 egg out of the 24 that doesn't show this sign. One of my D'Uccle eggs. But.. We have another issue. It is a twin. The first time I have actually viewed 2 embryos inside an egg. From what I have read however, it is very rare for twins to ever progress to hatching. Let's hope on a miracle ;)
Here's a look inside. It's not the best quality but if you look close you can see a dark circle to the left and another to the right. They are both attached to blood vessels and moving.
