MR. Smoky, the Cuckoo Maran looking cockerel! Lol.
ETS: Could we perhaps get an up-close on the hackles and saddle feathers. That tail of "his" makes me wonder, and maybe a picture of him not excited? My Cuckoo Cockerel looks a bit different than Smoky here.
I am going out on a limb on the gender and say hen, reason being is that I see no hackle and/or saddle feathers, and I have barred rock hens at 20wks that have wattles and combs twice that big, so I say hen as far as breed I am certain she is not a barred rock, but not real sure what she is.
