Hi there! I went to purchase 2 ducks, but the farm supply only had 3 left and I couldn't leave the littlest one all by itself. The cashier said, "it's ok cause this one is a mallard and will fly away anyways; then you'll have the 2 you wanted!" is this true? I'm scared to bond with it because if it does fly away I don't want it to end up as someones wall trophy (GROSS!!) - so it should be scared of humans??? it's so sweet and actually doesn't mind being held and the 3 ducks get along fabulously - I cant imagine the littlest one picking up and leaving its friends - but I suppose nature has it's own ways. any thoughts?
