No. Hens will lay more when there is less stress put on them, and having roosters - especially too many per hen, too large of a rooster, aggressive roosters, etc - will cause the hens a lot of stress.

The amount of roosters needed for breeding hens is about one rooster per ten hens
You can tell a roster apart from a hen by their physical characteristics. Roosters typically have larger combs, wattles, and spurs than hens. They also tend to have longer and more colorful feathers, and they often have a more upright and pronounced posture compared to hens. Additionally, roosters are known for their crowing, while hens typically do not make as much noise.
