Roosters are one of the most mistreated, abused, neglected, abandoned, and unwanted farm animals in the industry today. Male chicks more often face slaughter shortly after hatching, and adult roosters face a high chance of being mistreated and/or unwanted. Some don't like the crowing at all hours of the day and night. And it doesn't help that many jurisdictions have outright bans against roosters since many that allow “backyard chickens” only allow hens, not roosters. There is also the stigma that roosters are aggressive and cannot get along with each other.
All this puts roosters in a bad spot, and they are our NUMBER ONE requested intake BY FAR. And we just can't say yes to everyone. But there ARE options! Roosters have wonderful personalities and can absolutely get along as in a rooster-only flock.
Below are some links that we think provide very useful information to set that option up:
