Had a batch of quail hatch over the weekend.... two eggs failed to hatch at all.

Cracked them open last night when it was obvious that they were not going to pip and one was a yukky undeveloped egg..... in the other one was a not long dead chick.... with its top beak mandible all curled round to one side   It also appeared to have no eyes
 
Does anyone know what may have caused this deformity.... or if it is just one of those things??

They didnt get overheated at all..... I have a min/max digital thermometer..... But the only thing I have seen that might have caused deformities is too high temps
