Peekin - add to camp Kenmore, your flock is going to be highly stressed, and your pullets run ragged. In fact, I think I would pull all three roosters into the bachelor pad, and see how they grow up, later when your hens start to lay, you can pick your favorite rooster and add him to the flock. Pullets are not ready for a rooster until just shortly before they lay. A mature rooster will ignore them until getting the right signals. Immature roosters will mate anything they can catch as often as they can catch them. I find a rooster that is close to a year old or more is the best roosters to put in a flock.
