I'm new to chicken raising. I have 9 chickens and 2 ducks all 17 weeks old. There's 4 Barred Rocks, 2 Rhode Island Reds, 2 Brown Leghorns and 1 Buff Orpington. I don't know what the ducks are. When we went to the feed store someone had stolen all the signs identifying the chicks. I was just hoping I got all girls.
