Capons will not sit on eggs.yeah this girl said they become mean to hens and sit on eggs all dat
In rare cases, they will brood baby chicks. Around 1910 or so, farmers would use a capon to take care of baby chicks so the broody hen could go back to laying eggs. This was before modern incubators and brooders were developed!
They are not mean. They are like sissy chickens. They are usually lowest in the pecking order below the hens.
Capons need very secure housing, because they will not fight back against predators.
