I agree with a lot of what has been said here. We live in the city and only have three little chickens but they have ended up being a great addition to our home. This started as a project for the kids and me and hubby had nothing to do with it, other than helping to build the coop/run. As they've grown, hubby's love for them has grown as well. He enjoys sitting out in the yard with them running around his feet. He talks to them and lets them sit in his lap. If I'm caught up in something else, he remembers to lock them up without me even mentioning it.
They do poop, a lot! But, that poop is gold in the garden. My lawn is very green without any additional fertilizing. We scoop poop in the coop/run daily so there is no smell. When I completely clean out the shavings, they go into a compost pile that eventually makes its way into the flower beds and veggie gardens. Both are doing really well! There are almost no pests in my yard and for the first time I have a very lush, bug free patch of lettuce and salad greens.
And, no one likes store eggs any more because they are bland and tasteless. If you've ever compared a home grown tomato and a store bought one, you know the difference can be huge. It's the same with a fresh egg from hens that live happy and carefree lives in my backyard.
Start small, with just a few hens that are good and early producers. With the right hens, you could have tasty fresh eggs in as little as 4 or 5 months. If it works out well for both of you, you can think of adding more later.
