Lots of chickadees called today, they r starting to establish their territories for the up coming breeding Season. Really nice to hear themIt's nice to see him again. I'm so tempted to put the bird feeders back out. I miss all of my song birds badly. It's just too quiet around here.
I keep an open mind too:
Hope you have a gentleman for a rooster. You might benefit from reading any of @Shadrach 's articles, he is very knowledgeable on hen/rooster/flock dynamics. Hens invite a roosters attentions and a good rooster respects the hens.
I too have no experience beyond what I have learned from @Shadrach and @RebeccaBoyd, what you say here sounds right to me.
You forgot🌪 here’s some noise making items. (I’m only trying to help)

Sorry
This could work, but you also would not need to keep the boy in with your breeding girls 24/7. He could just visit the girls every couple days for a short period to service the ladies. If you have them all free ranging now, and different breeds of Roos with them, first thing your going to want to do is lock your breeder girls up for roughly 3 weeks with no boy. Since hens can store sperm this is your clean out period. After 3 weeks take your selected boy, put him in with the girls for maybe a hour at most every other day since their coop will be on the smaller side. Wait a week then start collecting and storing their eggs for incubation that way you know for sure who the father is. This is just one method I was told about and I would prefer it over keeping the boy in with the hens locked up in a smaller space.
It's our little secret.
