Help! My Duck hatched 8 ducklings. (She had 10 eggs and already threw out and killed 1 right after it hatched). They all hatched 2 days ago and were perfectly healthy, then this morning I saw that she threw 2 of the ducklings out of the nest and drowned another one. Why would she kill a 2 day old baby? Does she have too many and can't handle it? Should I take some of the ducklings away and put them in a brooder box? I don't want her killing more of them. Thank you for any help/advice you can give me!
