I know these are your beloved chickens and it sounds as if you have three options. I say three because even though I see no problem with it, I doubt you will go with the caponization method.
1) Make a seperate pen for your roosters.(who may later turn on each other??)
2) Get more hens ( you can order pullet chicks only from hatcheries)
3) Find new homes for your spare roos.
If you truley love them, whatever the best decision is for the roosters is the decision that needs to be made. To not get rid of them because you love them so much, is just being selfish.
I usually don't have a problem letting go of a pet, if that's in its best interest and I have plenty of animals that I cannot seperate with. BUT, they have the appropriate accomodations and flock mates.
ETA: Even though i consider myself a religious person, I highly doubt prayers are going to change rooster behavior.
