I'm down to 3 hens. Plan on getting a few more. As PorscheGal says Backyard chickens is a great resource. I clean the coop & run out every morning so no smell, (they are more like pets with benefits
). Here's a pic of my coop and run.
I even ran electric to the coop. I leave lights on in the winter so they'll still lay eggs. Chickens need light in order to lay.
