All of my heritage RIR cockerels are between seven and eight months old. Their hackles and tails have gone through the five month old molt and are nearly grown in now. I say nearly because HRIR take a full year to mature. They still have feathers coming in.Mumsy how old was that boy?
Is his lack of tail normal for a six month old Orpington roo?
I don't know anything about Orpingtons.
