My flock is 8-11 months old, 9 female, 1 roo (11 mo). I simply love and adore my roo (Spatch is his name) but I don’t pet him..ever, since the time he started crowing. I address him by name and walk past him and his nearby ladies as I do daily chicken chores. All treats are presented at his feet or nearby so that I’m not seen as competing. When I have to inspect hen during the day I bring her back and put her down near him. My methods have worked for me so far. I learned here on BYC that cuddling a roo, young or old, may not always work out safely, so I decided to look without touching early on. Hope your boy settles down and you remain unharmed.
Hens go broody when you don’t want them to… and won’t go broody when you do.
