I purchased three Rhode Island reds from TSC almost 6 weeks ago. I’m questioning if one is actually a Rhode Island Red and if it is a roo too. It is larger than the other two and has been since about three weeks old. Its comb and wattles started coming in much earlier as well. It has a cute little Mohawk which is reall what makes me question this. These pictures are from 4 weeks old and then again at 6 weeks. So what the heck kind of chicken is this and is it a roo??
