New ducklings also need to be brooded.
Thank I've brought 5 the same age as my lonely little girl all settling well .If you are getting ducklings you will need to slowly let them meet. You might want to put the ducklings in a little play pen of some sort so they cannot have contact but can just see each other. Ducks are very social so I would think they will be fine with new ducklings you will just need to take it slow. Good Luck!!!!!
