I've looked at the city ordinances and we can keep chickens in our backyards.
I know how to build things so I can make the coop instead of buying one. I can build one for my grandparents if they ever decide to have chickens.
I like to look up how to take care of animals before getting one and I have a long time before I can actually get a chicken. In the meantime, I can always learn more about raising chickens.
