Here are some more pictures! Yeah the far left black one (Barbara Jean LOL) and middle one (Sour Diesel) I was sure were cockerels and knew that the buff (Bubba) was pullet, but after reading comments and unsure of the two on the far right!
I am fairly certain now of who are pullets/roos, but just want others' opinions on sex.
Also, the grey one has a weird comb-looking thing very different from the other, does anyone know what that is?
