While it is possible all 4 may get along fine, it is far more likely that scenario will not work. The cockerels may not tolerate one another and constantly fight. Or they may get along fine but harass the pullets to the point where they cannot eat, drink or dustbathe in peace. Having 2 hormonal cockerels constantly chasing them may stress them to the point where they quit laying. Even one cockerel may cause issues.If I keep both the roosters and hens together, will it cause any major problems, and will I get fertilized eggs?
