A rooster doesn’t directly lay eggs, and many people see them as useless. However, it plays a vital role in producing chicks. By producing more chicks, you can increase your flock, and these chicks can later become meat birds, egg-laying birds, or dual-purpose birds. Hence, this can benefit you in the future.
In addition to this, a rooster is aggressive, and hence, it plays a vital role in protecting your chicken flock against several predators. Other than this, it is insignificant and can be your source of meat. In short, it may be useful to be added to your working flock.
