I know they say that too... but some info says colder temps do get more girls the temp was pretty cold and results in a % of deaths of the fertilized eggs so it is surmised those were boys there is an experiment thread on BYC on this. Also some hens just seem to produce more boys or more girls. There is actually science studies behind the gender not working out 50/50. In a big Hatchery it is harder to fiddle with these variables but you can try with smaller operations to figure out which hens seem to produce boys mostly but you would need to set up breeding pens like they do for gamefowl so you know exactly which hen laid which egg.I know they say sex is not influenced by incubation temperature,but something sure influences my hatches. I'm ALLWAYS heavy on males . 50/50 not even close.lol
I've commented before that science is still catching up to "wives tales"

Other fun but iffy methods... egg shape some science is now backing it but it is really hard to do reliably but the science folks want to create a machine that measures the eggs and discards the male eggs so the industry incubates less males... so not the total hokum we were told it seems, phases of moon and zodiac stuff, weather effects this I got to think includes more than temperature but also humidity barometric pressure, possible seasonal effect could have to do with hormones of the hen and or light, pendulum presexing the eggs...
Pretty much all of these are on BYC somewhere, some are just fun, or help organize ones chores I think. For more of the could be ones they might work together.
I thought of diet too, in many cultures there are foods they don't feed women to try and skew the numbers toward boys as certain foods are suppose to create girls others boys... sounds crazy, but not totally untrue, women's body chemistry at the time of conception can be more hostile towards one gender of sperm over another... people tend to do to their livestock what they do to themselves... so there is no doubt some traditional folklore on feed too. I know the hen decides gender, just saying there is probably no no lists of foods that could be tried on hens to see if you get more boy or girls.
