I have 10 hens in a chicken tractor and i was wondering if getting 2 ducks would be bad. I have been reading a lot on here and i know they are VERY messy but i think i can handle it. I have spare time and like today i was bored and just sat outside with my chickens. I have a couple questions i couldnt get 100% positive answers to on the internet. 1. Do ducks have to have water to swim in? Would they be okay just living like a chicken. Since my run and coop is moveable they will access to fresh grass. I guess i could get a cat litter pan and fill it with water for them... 2. Can ducks eat the same food as my chickens? I feed my hens layer pellets. 3. In your opinion what is the friendliest egg layer breed of duck. I would mainly want them for the eggs but i want to make sure they will be nice to my hens and to me. 4. How much room does a duck need in the run and in the coop? 5. Do ducks need special nesting boxes or will my chicken nesting boxes be ok?
