I have raised ducks and geese for 25 years- but am still learning. I have visited a few forums and joined two. This is by far the better for waterfowl.
I have read so many books and websites, and asked so many questions, and there is conflicting information in some areas.
But if you have the basics right- food , water, adequate shelter, you are off to a good start- and there are always people on here only to willing to help out with advise.
