Cockerel. And I would say Jersey Giant, I’ve had both black australorp and black Jersey Giant hen and he looks just like my Jersey Giant hen(but with a fancy tail!)
Thank you kindly folks! We inherited some hens and this is now our second generation of chickens. Not sure what we will do - I've contacted the farm to ask us either to be reimbursed or preferably for another hen! We are not allowed to have roosters in our area so he will hopefully find a good home somewhere.
