It's happened. We finally have decided to build a fence to contain the chickens.
They have developed a nasty habit of hanging out around the house, pooping all over the walks, coming through the dog door into the garage to eat dog food (and pooping in the garage!), dig up my flower beds, and with a whole world of beautiful green grass and clover to munch on they decide they'd rather eat the newly sprouting hostas and daylilies.
We decided that the cost of fencing in the chickens is much less than the cost of fencing in all of the gardens. I find that chickens are very destructive to a garden!
We're planning a very large enclosed area so they can scratch and peck and do their chicken things and we'll bring them all the weeds from the gardens for fresh greens.
The end result is that I can actually have nice landscaping, I don't have to fence around every single garden (that's a lot of fencing), and the kids will be able play outside with bare feet!
... one other bonus is that the chickens will be more protected from predators. Red-tailed hawks are a big problem for my chickens (that's what killed our beloved rooster, Pants On The Ground) and I plan to run strands of fish line across the top of the enclosure to discourage the hawks.
