I'm a first time duck owner and I have 5 Swedish. They're all relatively young and not laying yet. I've noticed that lately when I head down to the chicken pens, wild ducks come flying out of the pond my ducks are in. My ducks seem fine but I just wonder if this isn't good? There were about 15 of them last night. They're not bothering me and we only feed my ducks once a day and only as much as they can consume within 30 minutes or so so they're not eating up all the food. I just wonder if this is safe? I'm guessing that my ducks will eventually be larger than these little wild ducks.
