We have about 25 chickens right now and we just picked up another 18 chicks today. Our's free range on our land and they're fantastic at keeping bugs down.
We've had some problems with snakes, but we're in the country outside Austin, TX and snakes are just a way of life out here. We even had to remove a rattlesnake from inside the house a few weeks back. Skunks are a big problem this year -- lots of them out and about.
We give and sell fresh eggs to everyone we know. I routinely take them into work and sell them for $5 a dozen. We've had to explain the whole not washing or refrigerating them to most people but after they've had fresh eggs they always want more.
