I finally figured out how to candle But now I'm not sure what I am looking at The black spot in the "yolk" means it's fertile, right? I have some that I cant find the black spot but have veins surrounding the shell, does that make sense? Are those fertile? It has been 7 1/2 days since they went in. Is it possible the ones that look blank could still be fertile? What about turkey and guinea eggs? Does it take them 7 to 8 days to show fertility as well. I know it's 3 weeks for chickens to hatch, 4 weeks for turkies, what about guineas? Questions, questions, questions, one of these days I will figure it out.
