Well, it is kind of a general rule in life, BUT, as far as peas go, cocks do not spar or fight when there are no hens present. Hens do tend to lay their eggs in poorly thought out places and will cause you worry for about six weeks until the chicks can fly up to roost with mom and siblings if she doesn't get killed by a predator first. We free range about a dozen peas and they are such a joy to see living as nature intended for them to live. However, we will run most of the hens into a pen for the breeding season and the few we let free range we watch carefully where she sets her nest and take the eggs once she begins to go broody. Sometimes we will pull a lot of dog hair and make a circle around her to help hide her scent, but it is still risky.
