That IS adorable! I know that some of my current flock are Runner mixes, who knows what will come out of them.
I used to think Muscovy were ugly. Well, too many caruncles still turns me off, but I now find them to be absolutely amazing looking. Probably their personalities.
Speaking of, I've been noticing that, overall, my drakes are much friendlier towards me than my ducks. They seem to be more curious and inquisitive, and willing to approach. This is in both Muscovy and the Mallard breeds.
I agree, Fall is my favourite time of year. I love the colours and the smells! Only thing I dislike is it means winter will be here soon...
