I recently purchased three cayaugas and 6 silkie chickens. The pen I am building will be 4 feet by 8 feet, with the "living" area about 2 feet off the ground and the "pen" underneath. The pen will be open to the elements but enclosed with chicken wire or whatever I end up using, with a ramp going up into the coop area and a door to my backyard. They will be freeranged during the day and put in the cage at night for protection. In an attempt to keep the living/sleeping are of the coop clean i was thinking of not keeping food in the upper enclosed area, but instead in the lower portion of the coop. If I used chicken waterer nipples in the upper area will the ducks drink from them if they get thirsty? I will keep food and water for the ducks to eat in the lower portion because I dont care about the mess but would perfer the ducks not mess up the upper area if possible. I have no issue leaving the ramp open all night so the ducks can eat if they want. What do you guys think? Thanks.
