>>eggs must be sorted before birth. How does that work then? Do we already have technology to do this?

The Circuit uses a laser to create a tiny hole of 0.3 mm (0.01 in) in the shell of all fertilized hatching eggs. A minimal amount of allantoic fluid is then extracted from the hatching eggs and placed into an external marker. From https://www.respeggt.com/technology/ https://www.respeggt.com/technology/. According to their own site, they are a for-profit organisation incorporated in Köln, are focused on humane poultry and appear to have invented this technology.

I'm actually incubating my first round of eggs today and we're trying to get an 8:1 ratio of hens to roosters. I found a paper from the early 1900s that documented the old way of sexing eggs. After the egg is laid and has cooled off, a bubble forms in the wider end of the egg. If you candle the egg the bubble will either be centered in the end of the egg if its male, or the bubble will be offset and not touching the end point of the egg at all. No clue if it will actually work but interestingly enough we did get roughly a 50/50 split from our chickens. I guess we'll find out in about 9-12 weeks if the trick actually worked!

  I'd have thought you'd be able to simply look at the egg and determine it, given your username.

  I would like to learn about it, too. Please. Could you post a link where you will tell about your experience?

The paper is from 1921, this page should have a link to the full text. Just started our incubator today with 24 female eggs and 3 males per the bubble, we'll see what happens!
