I hatched out nearly a dozen Sultans between yesterday and today. They were shipped eggs. 2 didnt hatch, but were fully developed and dead in shell. I broke open the eggs to see what may have went wrong. Sure thing, one chick had a shortened upper beak and half of his face looked like it was pushed in and badly malpositioned in its shell. The seconed chick, also had a shortened upper beak, sunken in eyes, the rest of him looked normal, but also malpositioned. This is not the first time I have encountered this, but the sencond chicks brain was completely OUTSIDE on the top of his head. Now that is very disturbing when I encounter the unhatched chicks with exposed brains. Does anyone know how and why this happens sometimes and how the chick can fully develop until pipping stage with his brain exposed? This deformity has got to begin within the first few days of incubation. However, I keep the incubator temps and humidity levels on target throughout incubation. So, I know that isnt a contributing factor.
