I have a swede but we thinking maybe some Mallard may be in it too. We're thinking a drake but it's still young and does'nt have a uniform chest like swedes should,though I don't know how many you get that are perfect in a batch unless their pure.I've also noticed that 2 out of 3 have a lil' white eyline is that a sexing thing or not? Either way it's a gourgeous bird,I love the teal outline on it's back feathers! My lil one is starting to get green too.
