i just came back from TSC and got 5 Plymouth Rocks. It wasn't until I got home that it occured to me that I didn't even ask if they were pullets or straight run. I called them and they are straight run. :::sigh::: So I could potentially just have purchased 5 roosters. How old are they before you can tell if they are roosters or hens? I may have to put them on Craig's list if they are roosters. Bummer.
