One of my muscovy went broody on one egg (silly girl)... so I decided, on a whim to put some of my mixed duck eggs I collected that day under her just to see what I would get. I didn't do any breeding projects as planned this year, so no one is penned separately and they just breed with whomever they want to. I only put 6 eggs under her because I didn't want to be over loaded with ducklings since I have so many muscovy ducklings right now.... Well OBVIOUSLY my Black Swedish Drake was a busy boy. I'm pretty sure all of them are mixed with Pekin... Looks like my Silver Appleyard is the Daddy of one...But look at that little blue gray one... I just love him.
