It all basically depends on the dog. Our boxer hasn't been allowed near the chickens but I know if he did get one in his mouth all he would do is gum it a bit.... Our other dog is another story. This dog is old and set in his ways, I had an injured chicken and put her in a large hutch that i have. I didn't even think anything bad could happen to her in there but I found her in my driveway ....nasty sight. The old dog had literally broken into the hutch! GRRRRRRRRR I wanted to shoot that dog (my own) but I realized that it is just part of his"nature". So all in all it depends on the dog.
