hello fellow duck lovers! This is my first time owning ducks besides when I was a little girl. So needless to say, I have a lot of questions! I got these two ducklings one week ago from a local feed store. I was told they were both 2 days old. They were very close to the same size when I got them. Now the little yellow Pekin is huge compared to my other little guy (who my 5 year old son named Mr. Quackers Feather Bottom). I'm wondering if Mr, Q may be a Mallard? Can anyone enlighten me? Thank you!
