I recently lost 20 chickens and 3 ducks to some type of predator. I found no chicken feathers and only one dead, wet chicken. It ripped a huge hole in my duck pen. I have put out trail cams and haven't got any pictures of the creature coming back. My father-n-law put a camera about a mile from our house and got a picture of a large bobcat. My birds are officially on lockdown in their run. I was wondering if there was some other types of birds I could put with them to protect them.
