I've seen several posts that say people can sex a chicken egg by how round it is. Has anyone ever measured this? I have a digital caliper that I use for reloading and I can measure the width and length of an egg very precisely. I'm guessing that there is a certain ratio of width to length that would be the limit between a hen and a rooster. Has anyone ever tried this? I'm guessing I could measure all my eggs and calculate ratios and then based on the hen / rooster ratio I can figure out how many eggs are above a certain ratio to give a certain number of roosters. Then use this limit in my next batch of eggs to be sure I have the right number of hens and roosters that I need.
