We are planning to use a 12x12 chain link dog kennel for a run for our chickens and ducks. We will be moving them outside soon. The floor of our dog kennel is cement and we planned to move it off the cement about 3 feet so they have some dirt and we will put pine wood shavings over the cement, Is the cement okay for chickens and ducks? I will have a coop and a duck house but I plan on them sharing a run, I'm not sure if that is a good idea or not. Also, is the chain link enough to keep out any unwanted visitors? We are new to raising chickens and ducks so we are trying to get as much information as possible before we move them outside. Any input would be appreciated.
