Well....while you DO need a roo to fertilize the eggs, unless you have a hen who goes broody on you, you have no worries of babies. Not sure if someone told you that with a roo you would have babies coming out your ears...lol. I have one hen, Zoe, out of 8 who so wanted to be a mama, she would not lay, sit on eggs and i would have to push her out and make her go eat, but she got her wish 2 weeks ago with 6 new babies.
Honestly, Chief is not loud or obnoxious at all. I just talked to another neighbor right next door and she said he isn't a problem at all, that she rarely hears him, and even then it isn't often if they are outside.
Can't wait to see when your babies get to be adults, wait till you get your first egg!!
I had two extra roo's and I put an add up on Craigs List and they both went to good homes, my favorite roo, Pipin, is only about a mile away.
