I think the sooner you remove those roosters, the better. Like in a few hours, not a few days. Your ladies deserve better then this, and you are the only one who can help them. Trust me, after it is done, you will have no regrets and wonder why you waited as long as you did.
I can also say, that how ever difficult it is to butcher a problem rooster, the peace and joy you and your hens will experience in his absence will leave you with no regrets.
Taking a life is never easy, but I think you are making the right decision. There are many good roosters out there, and shouldn't settle for one that is injuring you and your family. Taking out the mean ones, means giving the good ones a chance at life.
The butchering may be fairly...
