Omelet's parents were given to me as "mystery eggs." Dad hatched from a pink egg & mom from a normal brown egg. My guess is there may be some Marans & Easter Egger in Omelet's mix. Since DD called the orig chicks her "babies," she calls Omelet her "granddaughter." Although the roo was sweet & non aggressive, he crowed a lot & mated the hens bald. Before we gave him away, my daughter hatched several eggs he fertilized to choose a female offspring. The mama hen was also a fav, so DD set more of her eggs to be sure we got some sweet personalities.
What I found very interesting was the female to male chick ratios. It should come out to 50%, but we tend to get more females in every hatch. (This was not part of DD's project, just my own curiosity from the data.) When I looked at each hen's indiv offspring ratio, I noticed that the same hens who produced 2/3 female in the 1st incubation, did similar in the second & third hatches. My fav hen (Omelet's mom) gave us 7 male & only 2 female chicks. This makes me wonder if there are ways to increase the number of females hatched. Any theories?
