Have you ever noticed any kind of vein pattern when candleling? I've been curious about the articles coming out of Germany that they are inventing a way to find out the sex of chickens by the vein patterns in the egg. They use a certain machine and insert a device into the egg at day 3 of incubation. I've never incubated, but I am curious if anyone has noticed any kind of vein pattern by candleling that might let you conclude either way? Here is one of the articles I've read about: http://www.thepoultrysite.com/poultrynews/34741/germany-aims-for-chicken-sexing-in-the-egg-by-2016/ Just curious. Thanks!
