Right now I have 13 chicks and 4 ducklings. My black australorps seem to be the friendliest because they always think I'm about to give them a treat. The Cornish crosses are very rambunctious and are tiny bull dosers. My ducklings seem to be a little more distant, but cute none the less. I know they have a chance of getting more/less friendly, but will their personalities stay the same?
