Hi. My name is Dawn. My husband and I are raising chickens for the first time. We have 7 birds. They are about 4 months old. We were told we have 2 Rhode Island Reds, 2 Americana's, 2 Barred Rocks, and 1 Cornish Rock. We know we have a rooster, we've heard him in the morning the last 2 mornings. I have a suspicion to which one, but not sure. Also, can hens lay eggs without a rooster? I don't think our neighbors would be happy to hear him in the mornings? He are a lot of pics of my birds. Thanks.
