I have four buff hens and they are much fluffier but they are much older but as I look around for buff orp roosters I've started to notice the rooster and hen look **** near the same hieght being the one real difference the comb and waddles arnt much bigger specially at that age... Listen for the crow in the morning or if he's/she is trying to mount others that should give you a hint male chickens walk and manor isms are different too
