I am very new to keeping ducks so I am sorry for all of the questions. I am planning on getting 3 females in about a month. I have 4 chickens right now but I have had more in the past so I am familiar with chickens but not so much with ducks. Do ducks roost like chickens or do they sleep on the floor? How old do they have to be to swim in a kiddie pool? Can their beaks eat out of a chicken feeder when they are grown? Thanks in advance!
