I suppose the parents of this guy was an Australorp OR Black Sex Link and one of my freedom rangers. (I don't have any white roosters, but the only white chickens I have are Brahma or leghorn, and this roo didn't get any pea comb/feathering on legs/ and my leghorns put out all white chicks period). I would lean closer to my sex link, since their background has RIR/Barred rock, hence where the white comes from. Just some ideas.oh wow!
The buff one I got before was my Easter Egger and my Buff Brahma.
Anyways, what kind if comb does your chick have?
