No but in the dark-downed strain (this may only be found in the bantams) they are autosexing to a fair degree, probably 80 percent. Female chicks have defined stripes while males have a grey back and whiter wing tips. There are a lot of questionables with this method, however.Are Buckeyes sex-linked? My two Buckeye chicks Erie and Kaska were two weeks old and had significant color differences, with Erie (female) being a bright tan and Kaska (most likely male) having a darker brown coloration. They both have the slate underfluff, so they are probably pretty pure-breeds, but I want to know. Also I have a picture, but my phone is being weird and not letting me post it, so I tried my best to describe the two. Thanks in advance!
(also Kaska is 2 months older now, and has a prominent comb while Erie doesn't so that's why I believe he's male)
