OK, I'm a geeky scientist and I have been busy with my new experiments in hatching chicken eggs! I've heard rumors that you can sex the egg before it hatches by how round it is and that the pointy eggs turn into roosters and the round eggs turn into hens. So my first experiment is to test this theory. The first thing I did was measure the length and width of the egg and calculated a ratio of the two numbers. I used a digital caliper accurate to 0.01mm from my reloading days. I calculated a number by taking the width divided by the length times 100 and rounding to one decimal place. A 'score' of 100 is a perfectly round egg and the lower the number the more pointy the egg. My scores were from about 64 to about 82. Then I weighed each egg on my kitchen balance accurate to 0.1 gram. I then used a pencil and wrote on the end of the egg with the roundness score on top and the weight in grams below. Then I organized them left to right with the pointy eggs on my left (lower roundness score) and the round eggs on my right (high roundness score). I then set a weight limit because it seemed that all of my very round eggs were underweight. I chose 45 grams for the weight cut off. Anything below that I considered too light. I had about four 18 packs of eggs to chose from. These were collected over the last four days since I get about 18 eggs a day. I wanted enough eggs to be able to chose all my eggs from at least half of the eggs on the right, the round ones. I'm assuming a ratio of 50:50 hens to roosters, so keeping with the right half should give me all hens. And keeping with the eggs that weight the most should give me the most healthy chicks. I'm supposed to get my R-Com 20 Pro with USB incubator in the mail tomorrow and I'm ready to go, I just need to add water and eggs! This will truely test the roundness vs. sex theory! I dropped and broke one egg while weighing (OH NO!). I've heard that pencil marks on eggs have no effect on the embryo. The 20 eggs on the top are the ones I'm going to use, which were selected from the four cartons below. I was three eggs short of filling them all as you can see from the last row on the left, the rooster end. Tomorrow I can replace this stock photo with the real thing!
