I am new to ducks and have so many questions, this is the best forum, I have learned so much! I got what was suppose to be three Pekin ducks, however one is alot smaller, has a puff on top of its head and is getting brownish feathers, Does anyone know what kind of duck this is? What kind of housing do you have for ducks, I cannot leave them out at night. Right now I have them in my chicken coop (our chickens have not arrived yet). I am enjoying my ducks, they make me laugh everyday! Thanks for your help.
