I think I'm going to have to go with my gut instinct on this and realize I have a rooster, or two! The one in question in this photo is the one on the left. They're the same breed and same age, about 7 weeks. For starters the suspect in question has a much bigger and redder comb than the other. He/she also walks around puffed up most of the time and chest bumps the other chick pictured. Just before I took this picture he/she charged and aggressively pecked my poor, sweet German Shepard. Lol. (I know, not funny but her face was priceless) I also have an Austrolorp in question whom also has a much bigger, redder comb and same build; but much much better behaved!! I think I'm going to have to come out of denial, call a spade a spade and realize that I indeed have a rooster on my hands. Any thoughts?!
