Three chicks come walking across your living room LOL. My girls are over two weeks old (will be three weeks on monday) and oh boy are they showing it! I knew I would have to expand their brooder this weekend because they are not happy if the lid is on and they can't get out of their current brooder. They like to get out and have the extra space in the mudroom. So they are going to be moved into a larger box this week. Just until I get a large old wire dog crate cleaned up and put together for their final brooder weeks.
