there are many feather-sexable colors including pharaoh, pansy, pearl, grau,egyptian, falb fee, some pastel?? those that are not feather-sexable include a&m, english white, scarlet, rosetta, tibetan, silvers/ssc, and all tuxedos. (other color gurus feel free to chime in if i’ve put any in wrong group or left out any).....those that are not feather-sexable can typically be vent sexed or “vocally” sexed by 6 or so weeks.aside from the breast color on the wild type are there color differences in the other colors of the coturnix quail so you can sex them?
