They do look normal to me, however I have hatched Fires that took awhile to really look like Fires. If it doesn't make a difference to you, I would say keep the babies and see if they start to get lighter as they get older. However, I would say that it is safe to bet they are normals. That doesn't necessarily mean you struck out on the male being a Fire. Maybe he is. The odds may have just been really NOT in your favor for this clutch. I would try to breed him again and if you get the same results then maybe he is just a really nice normal. I hope he fathers some Fires for you! Good luck!
