Is it true that a lower temp makes more girls?

    I heard that that lower temps affect ducks, but I was getting lots oflittle boys last year so I lowered the temp and I got ALL GIRLS!!! Does it work? I've gotten mixed answers, can you tell me truth?

    Actually I'm worried that it could have just web a fluke, A lucky break.

    Temperature does not effect what sex a duckling will hatch. Just like humans the gender is decided genetically. What can happen is that with a change in the temperature more girls survive than boys- or vice versa. For example- Start with 20 eggs - a 10/ 10 split of sexes is reasonable- but doesnt usually happen in such small hatches. Change the temp and you may get 12 to hatch with a much greater proportion one sex.

    Is sex always determined in every species through genetics? Because I have definitely heard that most reptiles' sexes are determined by temperature.

    Basically, the temperature never decides the sex; rather, it favours one sex or the other. Higher temp: boys will all survive, most girls won't. Lower temp: Girls will all survive, most boys won't. Something like that.
