We found these little darlings in our parking lot at work on sept 2nd of last year. We looked all over for Mom but they were found in a very urban area, and a huge storm the night before led us to believe they may have been washed down a storm drain and popped out of a nearby culvert. We had just bought a house in the country and brought them home and raised them as our own. We assumed that they were probably wild ducks native to Wisconsin, but as they grew it seemed more likely they were some sort of domestic duck. They never quack, they just make this sort of chirping/cooing sound when they are happy. They do it when they see their favorite treats or when I come to give them scritches. They seem quite happy and we have done our best to do all the research we can to make sure they have the proper diet and accommodations. They have about 2 acres to find snacky snacks on, a huge pen with a pool, and a hut to stay warm and snooze in. I think only one is female (only one seems to be laying eggs) the one with the black specks on her head. And holy cow she lays A TON, since she started this summer it has been roughly 90 eggs? None of the eggs have been fertilized so far and she doesn't care if I take them. I don't have a reference for what sort of duck they are so I can't tell what they are supposed to look like or weigh etc etc. Any advice is welcome, and I am still light years behind the learning curve. Thanks in advance!
