As promised, I said I'd keep you posted on the backyard chicken experiment (see - http://www.busycraftymom.com/2012/03/backyard-chicken-experiment.html )
We still love them! We actually wound up getting three more - so we have a total of 6. This seems to be our max - don't want to have to clean up after any more.
BUT, the little coop our friends gave us was way too small. It wouldn't have worked for the original three in the first place - we couldn't let the chickens run around the backyard when we weren't there (lotsa hawks in this neck of the woods), so they would've had to stay in the teeney weeney coop when we were in the house. Soooo, I built this amazingly beautiful big ass coop for them to live and run around in. I'm quite proud. It took about 5 times as long as I'd anticipated, but I did it 85% singlehandedly.
Basically, I made a big wooden cube with a little door and covered the whole damn thing with chicken wire. It was surprisingly harder than it sounds. And chicken wire is a bitch to work with. But I DID it :-)
