I think a Salmon Faverolle boy would be a wonderful addition to your flock!!
That said, I have 4 roosters and none are Favs. I have 2 EEs, a bantam cochin, and a light brahma. They are all very nice and good at their jobs, but my favorite by far is my brahma. You just can't beat him. He is always watching out for the girls, he breaks up squabbles, and even though he is huge he is very gentle on the ladies. None of that feather pulling. He will also sit in the doghouse with them when they're laying, whether it's to protect them or to cheer them on I don't know, but he is just the best! I'd consider getting one
Also, I owned a polish roo up until just recently when he passed away but he was not loud. I think I heard him crow maybe 10 times in his whole life. He was 30 weeks when he died but he started crowing at about 12 weeks.
