I have some sad news to report about the girls. Our neighbor came over a few hours ago, quite upset to tell us that his dog had killed one of our chickens. He was of course profusely apologetic over the situation. I let the girls roam around to get the bugs, and they love their freedom. They have no fear of dogs, having only really been around Sadie, so I am sure they are a bit like sitting ducks, er chickens. The next door neighbor's dog (a small cocker spaniel) usually stays on his side of the creek and has never shown any interest in the girls, but the chickens often go roaming and I think it was a classic case of her being in the wrong place at the wrong time.
Rest in peace, Hazel. The girls and Lachlan and I will miss you.
