Ok, pic 1 they all look like mutts to me but the black one is a pullet.
Pic 2, again mutts but my vote is rooster for both.
Pic 3 I just cannot identify, has the same colour like one of my malay pullets but colour does not specify breed in any way.....
Pic 4 Barred rock(gender = ? without headshot) and either a columbian rock or delaware pullet on the light one
Pic 5 mixed breed ROO
Pic 6 that is a pretty big comb from behind on that lil barred one so I would say barred rock roo! I am guessing these are the same 2 birds as in pic 4? Breed and gender guess still either delaware or columbian rock pullet on the light one.
