I ordered a buff roo from mypetchicken.com and received him as well as my two barred rocks and two new Hampshire red on September 7th as day-old chicks, so next week they will be 5 months old. We previously had a buff roo that died and our intention was to replace him, however I am beginning to think he may be a hen. He has pointed sex feathers on his neck but has a rather feminine top hat. When we got our first polish roo we were told he was approximately 6 months old and look much more mature and rooster-esque, but that doesn't mean we were given the wrong age. Just let me know what gender he or she might be!
