Not sure what it was. The pen netting is torn down and Cartman (Welsh Harlequin drake) had his neck broken. Wendy (WH hen) also had a neck injury. Some blood and some wheezing. Possibly punctured through. She is resting in a straw filled tote in the back room. If she makes it through the night I think she will be ok. At first I though she was a gonner, but she slowly perked up once I brought her inside. In suburbia it is easy to get complacent about predators. But there is no telling what is lurking in the alleyways at night. Still not sure what I am dealing with. I have a small have-a-heart trap so I will set that and see if I catch anything. There is also a small secure pen inside the run so they will get locked up at night. We should have been doing that all along, but with 7 ducks it was a bit crowded. Well crowded is better than attacked.... grrrrrrr.
