My household decided to raise backyard chickens about seven months ago. Until recently our little flock (four hens and an accidental rooster whose future is still being discussed) was doing well and giving us about four lovely eggs per day. I've been referring to BYC for tips and information ever since we got our chicks, but unfortunately I'm only just now registering because I will need to make use of your experience and knowledge in the "predators and pests" forum. We are down to one hen and the rooster. I have to go examine the scene of the crime again and will be making a post in "predators and pests" later today. Sorry for the dreary introduction, but I will very much appreciate any help in indentifying our chicken-slayer!
