Hatching more pullets than cockerels - WHAT'S YOUR SECRET? - Page 6

Has anyone tried the temp control method? I know temperature doesn't alter the sex. It only makes certain eggs viable while others freeze/bake. I would love to try this when I get an incubator but I can't seem to nail down any actual temps or times. I did see one thread that said temporarily dropping the eggs to 40 degrees would result in hens hatching while potential roos were froze out but it didn't say how long to leave them at that temp and no one has suggested a temp to incubate so the only/mostly hens hatch. I'd rather eat the roos as eggs then have to deal with the problem of too many roos. Too many roos leads to me desperately trying to find them homes before they wind up on my table.
Has anyone tried this or have the b/g ratios of fridge chicks hatched?
