Have taken on 2 pekin drakes that are 4 months old that I took from a rescue. I have not a clue about ducks so any advice would be great. How much do they eat per day. I give them flock raiser right now and wheat as a treat so they come to me.. Is a cement mixer container large enough for them to have enough water? I have a extra dog house that I plan to use for the winter, with straw, but they do not want anything to do with it? I let them free range all day and have not locked them up at night since I live in a sub any dont worry to much about them since they hide in the trees all day, plus when I had them in the coop with my silkies they tried to drown one of them.
