White chukar partridge sexing

[Fluidless]

My first time raising chukar partridges, white colour on top of that and i have no idea how to distinguish their genders, Even when trying to observe their head shapes. İs there a way to find out by checking their vents?

Yes, it's a bit harder than other poultry. Here's a excerpt from an article about sexing chuckars.
VENT SEXING IN CHUKAR PARTRIDGES
Sexes of chukar partridges (Alectoris chukar), and other species of partridge, are difficult to distinguish because the sexes often have similar plumage. A method for determining the sex of day-old chukars was described by Siopes and Wilson (1973) based on a modified vent-sexing technique commonly used for domestic poultry (Komatsu 1935).
According to Siopes and Wilson, sex determination is based on the shape of genital protuberance (Fig. 16-4). In males, the protuberance is large and either cone or heart shaped. In females, the protuberance is absent or is small and flat.
The technique of cloacal sexing involves placing the head or neck between the index and middle finger, and placing the thumb on the lower abdomen. Then, apply gentle pressure with the thumb of the holding hand to evert the cloaca and expel fecal matter. After the cloaca is slightly everted, the small genital protuberance on the neutral rim of the vent is examined under a bright light.
Manipulation of this area with the thumb and index finger of the free hand provides an optimum view for accurately determining sex. This technique requires much practice before a high level of accuracy can be expected.
