The chickens are 12 weeks old tomorrow and they are doing very well. We have let them roam around the back garden because most of the vegetables are finished for the season. (They have demolished the remaining chard, while completely ignoring the beets, which is good for me. I love beets.) I am not going to let the dog alone in the back with them for quite a while, he is having way too much fun stalking them. As you can see.
