I got two muscovy ducklings but one of them (which I think is a female) is not growing much. Her eyes are not centered like normal ducks, her beak was fine when we first got her but as she's getting bigger, the tip of her beak is not growing right. The top of it is growing upwards which makes it hard sometimes for her to eat. She also has to mimic the other two ducklings before she will do anything. She didn't know how to swim in the mini pool with the others until a few days ago. I have worked with her and have become her close but I really want to know if she is a special needs duckling or if some are just born like that.
