Boys will do ..that ..size each other up early . Long as Fabio remains submissive to To dex it will stay the same .How large is your flock? I have 2 cockerels and 9 pullets with absolutely no room or desire to increase the flock size.
My two boys have been sparring since 3 weeks old. The bouts are getting more frequent. No one is getting hurt. Dex always comes out on top. I think that's just because he currently outweighs Fabio. I have seen Fabio routinely tuning up the girls so I think he may be better at maintaining flock peace and may ultimately take over when he catches up to Dex in the size department. They only spar when free-ranging.

If you dont have a problem ..I wouldnt try to change it ..
