How big/old are the male and female? It actually hasn't been long enough yet for them to have hatched. Have you candled them? Do they look clear? rotten?
i don t have the precise mesure this is the second time that i found eggs in the enclouse, the first time was december 2016 they look like freshly layd 0 chalking
Depending upon the temperature in the incubator, it can take for 3 to 6 months for them to hatch. I had YF eggs hatch after 6 months that were smelly and black, yet they hatched out 3 very nice YF babies. I never toss eggs until/unless I'm absolutely sure they're not good. Have you tried candling them?
RF eggs are hard to candle. They have a thick white membrane under the hard shell that makes candling very difficult. I wouldn’t look for hatching until April or May. 4 mos. gestation
