I also have purchased several dozen eggs from Brian, and travelled out to his place recently to purchase two adult pairs, he has very nice ducks and many are from Holderreads stock! If your duckling with the eye stripe is from Brian it’s probably a trout or a chocolate mallard I hatched several either chocolate mallards or trouts from him, and it looks like I got some of both! And one of the pairs I bought from him has been producing a lot of trout as well, as one of the females I bought from him is trout colored.After hatch and one week later
He has very very nice stock!
