#1 may see #2 as the more dominate male. #2 is mating. #1 is staying out of his way.
Sometimes a less dominate male does not crow, tidbit, etc because of a more dominate male being around.
A week is not very long. He made need a couple weeks to get his confidence with mature hens.
Some of the best roosters I've had were trained by mature hens. They often teach the boys proper manners. The boy must earn their respect.
You could give boy #1 some time alone with the hens his personality might change.
Do you have somewhere you could contain #2 where he has shelter, food, water and you can care for him out of sight of #1? Give #1 a trial of a couple weeks with the hens?
This way you would still have #2 as a back up.
I hate to remove a bird when I don't know if I'll need a back up plan. They are living creatures. So many things can happen. Been there myself.
Good luck with whatever you decide.
