They are getting bigger all the time. We have moved them from their cardboard box and into our old dog crate. It works for now, but we will have to do something else soon. D is planning on building a good sized coop with a run, but we'll use an old dog house for a few weeks when they first go outside.
It's funny. We move in some circles where having chickens seems so normal that I forget to many people we must seem like aliens!
Here are a couple pics of our growing girls.
