I have a 5 months old, female German Shepherd that tries to eat or play very hard with my chickens.

I have this dog for a week and he is always inside my house because my chickens are around the house.

The dog bit a chicken and threw in the air and then she bit it again in the air. I catched her in the exactly moment, otherwise the chicken could be dead now.

I also have a cat that lives inside the house and she tries to bite him too.
