Yes. Bobcats and mountain lions/cougars. My next door neighbor raises chickens (for eggs) and last year he had several chickens stolen, one evening he saw it happen. It was almost dark, he was feeding his chickens which were in their fenced chicken yard. Left the gate pushed closed but not latched to fetch some straw from a nearby area. When he was returning, he saw a big cat coming out of the yard with a chicken in its mouth. Wasn't sure if it was a bobcat or cougar but it had to have pulled the door open, grabbed the chicken, and ran off. It came back a few more times over the next couple of weeks. A turkey also disappeared.
He lets the chickens run free during the daytime. Sometimes they will wander over to my property, which is fine with me. They mostly stay on the other side of the creek. I like to watch them and oftentimes during the day, if I am outside, I can hear them clucking away. For some strange reason, it's comforting to listen to them. I have considered raising my own but it is a LOT of work and not cheap. No thanks.
Last summer, we also had two bears wandering the property. One morning, I opened the front door and the trash barrel, which is inside the fenced-in front yard, had been tipped over, the bag dragged out and torn open about ten feet from the front door. The four foot high chain-link fence was bent where it had apparently climbed over it.
Not the first time this has happened here. One year, the bear tried to get into the house, at the front door and you could see muddy paw prints on the windows in the living room. My sister was here and watched it do that. She made a bunch of noise and it ran off. When it is dark and the dogs must go out, I always turn on the flood lights, check for animals before we go out and I always go out with them.
