Will the ducklings get sufficient oils from the hen's feathers to waterproof them? Or should they be kept from going into a pond or deep pool until they get more of their own feathers? Should you just wait until the hen gives up on them before introducing them to water, and to their ducky destinies? I'd like to try this, but I only have broody bantams. It would be really funny to watch a little bantam hen with big ducklings cuddling under her wings.
