    My last hatch were LOTS of barred rock.... (most can be sexed but not all....) my temp was set at 102 most of the time as it has been cold and I did not want a dip in temp... soooo most of my barred rock chicks have large white non defined "girl" spots on head. There is only ONE male looking one with a tiny defined white spot. whhheeeeelll I hope so.

    Of course this cant be for sure... can anyone tell if they think the temp can play a role who hatches and the sex of the chicks? what do you do in anything to "pre determine" sex of chicks? what can be done?

    (duh...... besides 50/50 guess...LOL)

    I have been wondering the same thing. This past summer I hatched 2 chicks in an incubator that were both males and then I had a hen hatch out 3 and they turned out to be all roosters also. What are the chances?

    You can sex reptiles by temps, but it does not work the same for chickens [​IMG]

    I wish it did...then I would always have just hens. Sadly it is the luck of the draw and nature....

    Quote:Absolutely not. Temperature can not change the sex of a chick. If it could ... think about it ..... all the hatcheries would be hatching alot of females!

    I tried to hatch 12 total eggs over the summer... all by my broody hens... all eggs that hatched and lived (9 total) were roosters!?

    So, we thinking that the heat might influence/change the sex or at a certain temp all roosters die in the hatcher? I guess one could argue that if you have a 50% hatch and mostly pullets yep temp can make a differnce other wise whatcha thinkin????

    Quote:You have that head spot thing backwards. The small spots are GIRL spots and the huge, splotchy ones are BOY spots. No, temperature does not play a role with avians, only reptiles.

    Trust me on the BR thing. I've raised quite a few from hatch and rarely get the sexing wrong. The pic below shows a BR cockerel. Sounds like you got a bunch of boys in that batch.
