How likely, or is this even possible?

[Chicken_Trainer2007]

I hatched out seven chicks (one didn’t make it) five are pure bred Japanese bantams and two are a mix between my old hen and Japanese bantam. They All have the same dad, but the thing is they are all female! My temperature was 38.6 I don’t think that matters but I’d love to know how this is possible! Me and my family are thinking spangle(the rooster) has magical sperm PLEASE let me know what you think, and how rare this is! Thank you!

Spangle does not have magical sperm. In chickens, the hen determines the gender of the chick. How old are the chicks, and can you post pictures?

How do you know they are all female?

I’m a breeder, and sell hens for egg layers and roosters for soup

It's unusual but not that unlikely to have only females from a hatch that size. Each egg has a 50/50 chance at being male or female. But 7 isn't nearly a big enough number for that to statistically carry over to a likelihood of hatching 50% males.

I think they meant what characteristics are making you say all the chicls are female. Except for sex linked hybrids and autosexing breeds it usually takes about 6-12 weeks to be able to accurately determine male vs female.

How have you determined their genders?

I have been sexing chicks by vent and wings and never misgender any within my 5 years or experience

But I mean he could still have magical sperm couldn't he?
