I couldn't sex them via except threw a costly dna at that age, plus my hatching season is over till next breeding season, perhaps check UPA and see if there is a breeder near you that sells whites.I am located in Edmond, Ok . Half way between Edmond and Guthrie. If they are within 24 hrs of hatching it is safe to ship them. I would not take a chance on anything older. I have received them at that age and did real well.
