I started with three Barred Rock hens a year and a half ago, but have only Harriet and Lucy now. I came home from the grocery store on a cold (for the Puget Sound) winter day and saw a red tail hawk taking off from the garden. I first thought, "Cool!" Then immediately, "Raptor!" Sure enough, the hawk had killed Eulalie and scared the other two silly - though, not witless. Harriet had muscled through the gate and hidden in the bamboo; Lucy hightailed it into the coop. Later that day a naturalist on the radio said that, with the cold, the predators will be out looking for calories. A warning I could have used earlier. I've been lurking here ever since I decided to get chickens and learned a great deal from this site. I registered today because I'm worried about Harriet. I'll post the details on the disease/injury site. I've gotten quite nuts about my chickens. The one disappointment is that they won't eat slugs. So, in the spring I'm adding ducks to my gardening staff.
