Khaki campbells are fairly friendly. They're excellent egg layers and produce on average up to 210 eggs a year or more. Some people have the experience that they are a nervous breed but the ones I've had have all been okay.

Hi! I've got khaki campbell ducklings hatching Friday the 13th if you're interested. You should also swing by the Vermont thread, we'd love to have you :)
