Hello everyone, I'm new here. I'm confused which breed our ducks is from... we ordered 10 golden 300s from METZER FARM at the end of May, now they are grown up, we can see blue or green feather on the wings, which is different from our old golden 300s. our old ones were sold from METZER too, they lay eggs everyday, work hard! they are light grey, no blue feather. I have some Picture here. can somebody help me?
