Good morning! I have 4 Light Sussex hens. They are around 5 months old and am concerned that one of them may be a Rooster. After reading lots of posts and looking at photos I'm even more suspicious that Harriet may be a Harry. Im just going off the black feathers around her neck. This chooky has much darker and longer black lace than the other 3. Although her comb isnt very big yet. Tell me what you think?
