So sorry to hear about your baby mallard!!! 

My little baby is no longer so little!!!! And he is being chased around by my mallard drake who is about 1/3 his size! Mallard got put in timeout for the morning. Any other advice to help them get along a little better? They have been fine together the past few days but our mallard female has been sitting on a nest out by the pond during the day (we tried moving it last night, she wasn't thrilled about that idea) when she is around the drake is much more "aggressive" (chases and nips at ducklings (7wks) butt)
This is Luke!
