Hens don't mind if there is no rooster. It is not at all an annoyance to NOT be pestered by a sex crazed male all day long. Especially vigorous roosters will tear a hens back bald with his...... endeavors. They will lay just fine without one, and fertilized and unfertilized eggs are nutritionally the same. A rooster is only NEEDED if you want your eggs fertile for hatching. They are good flock protectors, but a vigilant owner doesn't need one. Roosters can also become aggressive and dangerous, not always, but they are often not well suited for being a pet like a hen.
