We named my friend's cockerel Cornelius. It's the name of the corn flakes mascot, who was a welsummer.
Of course, my son got to name OUR cockerel and so we have the lavender orpington Captain Floofypants 😂
They are gorgeous boys at least! I ordered myself a lavender Orpington cockerel and he's handsome but most of the time I wish she would let me keep the welsummer!
Your welsummer is definitely a boy. Sorry. I'm raising 4 for a friend and we got one cockerel as well, also from Meyer. He looks just like yours and completely different from the girls. I'll add pictures so you can see the difference. The welsummer cockerels feather in very dark on the chest...
