Can u get a better pic of the side of the bird??? At this point a really good tell are the saddle feathers. To me at this angle "he" looks like a "she", but then again it's not a great shot of the side. We gotta be able to see the shape of the saddle feathers.
The tail also doesn't look rooster-ish....unless it's just holding the tail straight, I know my rooster was VERY OBVIOUSLY a rooster based on tail, comb and wattles, and saddle feathers by 5 weeks of age....
