Because it isn't banning. Did you even open the link? And I ABSOLUTELY believe there should be additional guidelines for all animals, not just chickens, because people are horribly cruel and don't care enough to provide appropriate space, housing, food, clean water, etc. Working in animal control, I am absolutely aware that there is not ENOUGH we can do to assure that animals are well cared for, especially livestock animals. The fact of the matter is, this isn't just a matter of property or your rights. These are actual living, breathing, feeling entities and it's about darn time somebody is stepping up to the plate to do something positive for them.
