I can't recall - is mom or dad the Spitz? And what color is the EE parent?
I just candled my Spitz-eggers yesterday and 3 out of 5 show development. Then I accidentally dented one (I dropped a guinea egg on it) but luckily it was one of the ones not showing development. Opened it up and it looked like the yolk was damaged somehow and I was relieved that that was the one that I cracked! I have them in the incubator and both incubators' turners have messed up on me at the same time so I hope I don't have any problems from not being able to turn them enough. My EE just went broody a few days ago so it looks like she will actually get to raise some of her own babies

I was going to give them to my Japanese broody but she will have to have a couple guineas instead.
