One of our friends suggest we keep all our chickens in cages raised from ground with wires at the bottom. For the following reasons: 1. To get pure bred eggs or chicks since people prefer pure breds than barn yard mix. 2. To keep them eating from each other's poo and other dirty things on the ground. 3. Keep them from disease carried by wild birds. He had hundreds of chickens, there used to be disease breakouts from time to time. He said after he kept them on wires he never get trouble again. But that seem to me to keep all chickens in jail, I like to see them free ranging, they look much happier that way. What's your opinion of keeping chickens on wires.
