Sorry to hear about your mother. You will find a lot of us here excited to hear about your ducks. What a great reason to look at more duck photos

.
They are beautiful ducks. They are going to love foraging. Give them time and you find them going further and further. Congrats on the first eggs!
In my experience, all ducks can be friendly. I find Cayugas and Saxony to be the most social. Muscovy don't like being handled, but go out of their way to spend time near you. I love my Pekin, but I wouldn't get them again. Too many leg health issues. They have great personalities, but sadly breed to live a short life. If you raise some new ducklings, we will all love to see photos!
