Hey ya'll. I just got 2 adult Muscovy Ducks and their 3 babies that I was told hatched on May 26, 2016. They are in a big pen with kiddie pools but the pen does not have a top. The dad, Daffy, has his wings clipped and they said the mom, Darcy, had not been clipped but she doesn't fly ever. To me her wings do look clipped. The biggest of the 3 have started "practicing" flying. He runs across the pen with wings out flapping them. What age do I need to clip their wings? I think they are older then what I was told. and also once you cut their wings once do you have to do it again?
