We got our ducks the Saturday before Easter, I think it was April 11. First question -- I read that male ducks will not change until at least after 4 months. Now, my ducks are starting to look very different from eachother and I'm wondering if it is possible to tell the drakes from the hens/females. It seems as though 2 of the ducks have a curl at the end, which I also read was a sign of a male. Those same two ducks also have very dark colored heads now, but I cannot tell if they are green in color yet, right now it just looks almost black. I just stopped to get some advice and see if anyone can tell me if these two are male. These are the two that have the darkest heads and the curls Here you can see all five. Second question -- Now, my ducks are free range, so they have their pond and their fenced in lot and they forage on their own and have taken up with the Geese that visit every year. However, I went to visit them after not visiting them for awhile, and now 2 ducks are missing feathers. I'm not sure if this is related to them being male ducks or not. But, since they are the only two affected, I want to make sure it couldn't be something else. Thank you!
