Sometimes the length of his spurs can help tell how old he is.She's totally broody
I took her eggs and left her sitting on her golf ball until I can get her spot ready.
Now .. I may have a problem ... or dinner
I let mama and littles into the run with the biguns tonight to see how it would go. Mama laid into anyone who got too close, including the rooster. He managed to peck a chick and that hen pummeled him. I was so proud .. but then he wouldn't let up with her. It looked like he didn't like her trying to push him around and wanted her to submit. I don't know how old he is .. was grown when we got him from a fellow church member.
You might be able to try an in sight time out for him, since this may be his first experience.
You may be right about it being pecking order between the hen and him. As he should still be at the top in theory. But I'm sure none of my gals would allow a boy to get away with pecking a chick. I do see the behavior of the roo change towards the broody... since she no longer puts out he isn't AS kind to her as usual. But I haven't yet faced your exact situation.
If he is gentile and good for the most part to the ladies... never dropping a wing to dance at YOU and not giving the stink eye when you pass... then he gets the benefit of the doubt and some training for the first go around, here.

Glad your mama showed tenacity!

Pics always welcome.
