This is my 18 week? Jersey giant. The eggs I've been getting are fertile ( bullseye is very prominent) and I think he is my rooster. I don't own any roosters whatsoever. But I think that he is. Hes got the cock stance and a hen squatted for him! He also bosses them around.

It match's up %100 with fertile. I cracked one that had been outside in the sun and it had some veins.
Here's another suspect cockerel Light Brahma.
