I'm in the city, so I only have 4 hens. They require surprisingly little maintenance and bring me great joy. And I was actually *afraid* of birds before getting the chicks. I took the leap partially to help myself get over this stupid fear and partially out of curiosity. Also, to help my kids learn that food doesn't come from cartons at the grocery store. And now look at me.... I'm the crazy city girl who wears heels to do morning chicken chores and hugs her hens every day.
For cons, I'd say:
1) Expense of building a nice coop. Yes, I know there are lots of you out there who got away with a $5 coop, but I'm not in that sorority.
2) Expense of keeping the girls warm in the wintertime. Again, I know there are those of you that don't heat your coops. See above.
3) Worry about keeping them safe. Chicken tastes good - and not just to people. They rely on me and I don't want them to pay for a stupid mistake with their lives. Doors must be shut and locked. Period.
4) Worry about health problems. I haven't had any serious problems, thank the Lord. But if something went wrong, finding help can be difficult.
5) Poo on my patio. Every spring I have to re-train them to stay out of the rose garden and off my patio furniture. If you don't free-range, this won't be an issue.
Anyways, the pros most certainly out-weigh the cons. My experience with the chickens has been so good, I now have 3 other friends who've gotten chickens too.
