90% accuracy means 9 out of 10, right?

why yes, yes it does.

It’s early. They’re only 4 weeks. But Roo’s comb pinked up last week and this week Roo has red wattles showing. The other four Australorp chicks don’t.

Is Roo appropriately named? (I know, post back in 2 more weeks...)

Middle pic is of Stella taken from overhead. Her comb is yellow.

On edit: if Roo really is a cockerel I may try to keep him. Technically I can have roosters but I also really like my neighbors.

Yup! Thanks a cockerel!
Handsome fella! ♥

Technically I guess it really means 90 out of 100. But let’s hope our chicks don’t know that.

Yes, I believe Roo and Stella are appropriately named.

You know, some neighbors might like the sound of a rooster crowing with no responsibility of it. I know I would.

You have a cockerel...and he will still be one in two weeks

True! I bought 10 chicks though so that 90% figure works just fine for me! I can’t imagine having 100 chicks! Every time I’m out in the run, I already feel like I’m in that scene in Jurassic Park where the baby velociraptors swarm that guy - and I only have 10.

90% chance means that each individual chick has about a 90% chance of being correctly identified as male or female, so each of yours has a good chance of being female. That doesn't mean you can't end up with 5 males and 5 females.
It's statistically possible to flip a coin 50 times and have it land on heads every time. It's extremely unlikely, but it is possible. There are a few threads on here where all of someone's straight run chicks (i.e. roughly 50% chance for male or female) have turned out one sex or the other.

And when one considers what the sexer id looking at, it's amazing it's that accurate

And now consider this is a vent the size of a day old chick, who is moving around as you try to hold but not hurt and you are doing several per minute......

You are dead right. I’ve watched videos of hatcheries vent sexing and those people fly through the birds. It’s short of amazing.
