I just put 7 duck eggs in the incubator Sat - problem is we are not sure if they are blue swedish or muscovy. Friend has both one of the muscovy ducks is currently sitting on a nest of 24 so not sure if this is another female or is the blue swedish. This nest was down towards the waters edge and the muscovy is 20 ft up in the oak tree (crazy duck)! The muscovy nest was full of feathers and you could tell was well tended - this nest was just a spot to lay an egg each day just burrowed down into the dirt - like what my buff / blue swedish used to build. Any ideas of how to determine if they are muscovy or blue swedish? I know they have different incubation periods so that is my concern. Thanks for the help!
