While I’m no expert on this subject. It’s my understanding is that Jake’s will breed but will not produce anything. But, if you have a lot of jakes they will drive the older toms away. They will gang up on the older birds. At the same time if there’s a lot of bigger tom’s they will drive the jakes as well as each other away. So it comes down to ratio of which birds have the majority at that particular time. Also the big toms will move with the hens that are ready to breed so in my opinion and experience here it varies on the factors mentioned here. Good luck..
