Consistently hatching more males than females

[PeepingK]

Second one looks like he could be a roo, comb development already. I feel for you, my last hatch I had three girls and five boys, they were from all different mothers. I think my olive egger only makes boys, . Also, I had one roo that was slow feathering, one girl that had fast feathering and the rest feathered out at the same time. It was fascinating to watch. At one point I thought I had one girl and the rest all boys

Yeah i noticed that too. At this point I’ll be happy with just 1 or 2 females out of the 10 lol.

Try doing some test hatches to confirm your theory that your Olive Egger lays only male embryos!

Cochins feather quickly and silkies feather slowly, so I tested the results of this mixture out on their chicks. Before reading up on sex linked traits, I assumed that the girls would take after their bantam mom with colorful fast feathering wings and tails, while the drabber lavender boys would slowly feather like their silkie father. Fast forward after spending $50 on DNA tests for the 3 three fast feathering colorful girls. (Back then my boyfriend used to push for DNA tests on any chicks we intended on keeping). The final results indicated that all three chicks take after their mom because they are boys! The speed of feathering is a sex linked trait connected to the mom. The other slow feathering drab lavender chicks turned into egg laying blue laced hens. We kept the pullets and rehomed the cockerels. Same thing with my sex linked cuckoo silkie chick, Princess. Mom happened to be a cuckoo silkie and dad a blue silkie. What sex is the chick? It should require another DNA test, but I didn't know back then. Colors and patterns such as gold, silver, and barred are all sex linked as well. Mom gives one gene to her sons. Dad gives a corresponding gene to sons and daughters. Daughters receive no such gene from mom. All females will remain hemizygous for sex linked genes, while males will be homozygous or heterozygous, so you will need to find out which features will dominate (e.g., silver over gold) to truly master sex linking. As a side note, slow feathering will not completely wipe out the fast feathering trait (as seen with my chicks), nor will silver fully cover gold (e.g., red bleed).
