How old is the female and is it her first time (I got 6 eggs from my female last year who I bred last July but she was just a year old and they were all infertile. This season she's given me 4 hatchlings with 8 more in the incubator that look good. If they all hatch, she will be my only 100% hatch rate female of the season)
Is the male fertile? If he's not proven, it may take at least another season with possibly another female to be sure.
Are your incubation methods OK?
Have you been experiencing the egg difficulties that so many of us have posted about?
have you good enoguht supplemantation with calcium nd vitamins?
That´s where I made an idiotic failure and my Raptor female laid 2 or 3 infertile eggs because of my fault.
