This is the first time Ive ever had sultans, I got a batch of chicks in the mail today and some of my sultans are pure white while about half of the other chicks are not. Is this normal? Are they sexlinked? Here is a photo below. You can see I also have silver laced polish. But I can tell the difference between them and the sultans as the sultans are feather legged and the polish are not. Yet some of the sultans as you can see have greyish chipmunk marks and patches of grey on the head and wings. While others are solid yellow/white. Sorry about the lighting. The brooder light is red.
