So I hatched two ducklings and the black one hatched first, while the yellow one hatched next. Well they are one day old now, and I have noticed that the black one is CONSTANTLY getting all up the yellow ones grill and pecking at his beak. I feel bad for the other one because it's exhausted! I think it could be a show of dominance, but still. The yellow one also pecks at the black one. Should I separate them or will this end? I have food and water in their and they know where to eat. I have never hatched two at once, so new to this. I just worried about the tired yellow one.
