    Hiya, Folks!

    Just in the middle of a successful hatch of 12 mutt chicks (BLRW roo, 6 different hens). We have 10 in the brooder now (yay!!!) and two left to hatch...

    What I am wondering is what the percentage of roos might be?
    What have your hatches been like...? Anyone end up with 10 roos 2 pullets?

    Also, some were cochins, but none of the new chicks have feathered feet. Is this a recessive gene?

    Five ee's hatched - will they lay blue eggs?

    Soooooo many questions!

    I've figured the odds for 8 chicks, not 12. Maybe this helps.

    Odds of:

    8 roosters 0 hens - 1 in 256 or 0.4%
    7 roosters 1 hen - 8 in 256 or 3.1%
    6 roosters 2 hens - 28 in 256 or 10.9%
    5 roosters 3 hens - 56 in 256 or 21.9%
    4 roosters 4 hens - 70 in 256 or 27.3%
    3 roosters 5 hens - 56 in 256 or 21.9%
    2 roosters 6 hens - 28 in 256 or 10.9%
    1 roosters 7 hens - 8 in 256 or 3.1%
    0 roosters 8 hens - 1 in 256 or 0.4%

    I've been wondering this myself. That info makes quite a perfect bell curve, doesn't it? I'll certainly extrapolate that for my expectations for my own "flock" assuming they hatch!

    Thanks for info,

    Laura

    I got 8 roos in my last hatch of 12 chicks. Go figure.

    I bought 4 day-olds from a buddy that had some, and 3 were roos. We had 5 silkies hatch and 4 were roos. We keep buying lottery tickets also, and haven't won a dime. Wonder what's up?
