I have 4 “baby” ducks. One is a month old with feathers just starting to come in, the others are almost fully grown. I have a drake who is clearly pure Cayuga. I have a female who I was told was Cayuga, but with many white feathers I assumed were due to age. My other female is Rouen. My Cayuga mom hatched my 3 older babies and my Rouen hatched the 1 month old. All my babies have a few white feathers so I am wonderering if the are full or mixed. I will post pics of each below.
