What to expect for Roos out of 20

[HensInTheForest]

We are starting about 20 chicks in 2 weeks.
likely 10 one week and 10 the following week we are not sure.

Is there chicken math for how many will be Roos?

Our Farm and Garden store buys from Hoover, McMurray, Cackle and a few others I didn’t know off hand.

90% hens so expect maybe 4 Roos per 20 chicks?? More or less depending on these breeds . . .

Breeds are 4 Orps, 4 EE, 3 Midnight Marans, 3 Prairie BB, 2 Light Brahma, 3 Faverolle, 2 BLRW.

I have 12 8 week olds from a farm store and so far only two roosters. I don't know if that helps but I always buy from the farm store (which I think in our case uses MurrayMcMurray) and this is the most roosters I've ever gotten.

If all are straight run, average is 1 male per female.

If all are supposed to be pullets, likelihood is 2

Like Jacin said, straight run average at half and half.
Usually big stores order pullets but there's always that chance of getting a misidentification or two. We got six pullet chicks three years ago and ended up with a cockerel, but that's not too bad.

A friend thinks out of her 8 pullets (for one breed, the others were all girls so far) she got 2 or 3 males

Out of 3 pullets from a different order, I have 1 that is almost certainly a male and another that may or may not be. But I purposely picked out one that I was certain was a male too in that trio
