Roosters

[Team01]

Have a question. I have four pens of chickens. Two pens has three roosters, the other two pens have one rooster each. Before they had roosters the hens were laying pretty good. Know the hens have dropped off in laying. Would it be caused by the roosters picking on the hens. Please help
