I always wanted enough land to do some light farming. I haven't got the land yet, but I figured 3/4 of an acre could hold a few chickens. Mainly I need to stay busy and this is just one thing I thought would be cool. I can sell the eggs to coworkers and have a few lower maintenance pets that contribute more than just pooping in the yard and licking me in the face.
We have rabbits, chickens, ducks and turkeys on 2acres.
