Hello everyone! First time here and first time owning chickens. I bought this bird at Tractor Supply 3 months ago and was told she was supposed to be an ISA Brown. I bought her at the same time as two Cinnamon Queens. She grew quite a bit larger than them and I bought several more chickens from a friend today that are two months older than her and none have the comb that she does... Is she actually a he and if so what kind?
