My husband and I have been raiding chickens and turkeys for 3 years now. We decided to add some ducks to our flock. We purchased 2 khaki Campbell's and 2 "assorted" ducklings from tractor supply a few weeks ago. Can someone please help me determine what breed my other 2 are? I'm including apic of when we first got them and pics from today. They are just now getting their tail feathers and wing feathers. Thank to anyone who can help.
