Hi! I recently got a chick (Leghorn) about 2-3 weeks old then the next day got 2 ducklings the same age (Muscovy). They live in the same pen and get along fine for the most part. Cuddle each other, etc, however, we just started noticing once in a while the bigger duckling will peck the chicks feet/wings and the smaller ducklings beak slightly aggressively. Should I be worried?? Or is this normal in baby chickens and ducks? And does anyone have any tips on raising them together?? Thanks!!
