Help! Problem of Death in Shell

[Siva]

I have been hatching my lovebird (Agapornis ficheri) eggs for about two years without major problems until it was about a month ago. Many of the embryos die in shell just before they hatch, No piping and it seems the yolk is not absorbed. I use an RCOM auto-turning incubator with 37.2 C (99 F) and 55% RH setting.

Does anyone have any idea what causes this? I have also attached a picture of my poor dead baby.

Thank you!

I know how disappointing it is to have eggs get to the finish line but fail to hatch. There are a number of potential reasons for DIS, hope this thread (scroll down) will be helpful: https://www.backyardchickens.com/articles/egg-failure-to-hatch-diagnosing-incubation-problems.67011/.

Best of luck in future hatches!

Thank you FoodFreedomNow! I suspect it is caused by nutrition but not sure which one.

I'm afraid I don't know know enough about lovebirds' nutritional needs to be able to opine...but if I suspected a deficiency in my poultry, I'd try a poultry multivitamin supplement to cover as many bases as possible (assuming the nutrients weren't already included in a formulated feed, or weren't at needed levels).

Is it possible that a nutrient toxicity also causes the same symptom?
