I'm new to raising chickens and just wondering; Is there any advantage to having a rooster if I just want eggs? We don't want to hatch eggs and we're not raising chickens for meat. We just want live chickens and fresh eggs. A friend told us that a rooster will help maintain order. Is this true? Is it enough of an advantage to make the crowing worth it while I'm trying to sleep. Would there be any other advantage to having them around? Thanks!
