You'd most likely hit the big one right off. I know TSC doesn't have female ducklings marked, I think they do it get pullets At least the one closest to us. Not sure about other feed stores.@Miss Lydia when his mom gave us marceline we had no idea what she was. She said it was the only duckling there and she felt bad that it was alone and bought it so we did luck out on her, when I went they had a bunch and the females had a band on their leg, do most feed stores not sex the ducklings? I think we may need to start playing the lottery I like luck
