So I got these 2 ducklings and they are suppose to be Muscovy. I was told they are the same age one is so huge compared to the other. The smaller one just seems off to me. It doesn’t go after worms when I feed them and it just doesn’t seem to eat like the bigger one. So I guess my first question is are they both Muscovy cause the person who sold them to me has call ducks also, and then maybe it just needs some vitamins or something. They are eating chick starter. If anyone has any ideas let me know thanks.
