I have a duck that is setting on her own eggs and 5 from a silkie chicken. Earlier this morning I saw her run from the coop where she's been setting on the eggs with something in her mouth.She brought it to their pool and dropped it in the water, much to my dismay it sunk to the bottom of the pool, when we dug it out we found out it was one of the silkie chicks.Is this normal behavior for duck mothers? I thought baby ducks couldn't swim till they were older.Something to do with getting wet. Is this their way of cleaning up their young? Will she do this with all of the eggs? Help me please I would like to save the silkie chicks if possible.
