I know this may have been asked several times on here but I'm curious. So I just finished up a hatch and wanted to know if the temperature determins the sex of the chick ? I also want to know if wing sexing is accurate ? I have 4 Lavender Oprhingtons. They are 3 days old now and if wing sexing is accurate I think I have 4 pullets. For the 1st 18 days the incubator Was set at 99.5 but stayed at about 100 forward most of the incubation. Can someone way in on both topics. It would be most appreciated. Thank you Bradley.
