I think my chickens are zombies!! Lol No...seriously they like to eat deer and deer brains. My husband got a deer recently and in the process of cleaning it lost some deer brains on the ground. He thought he got it all up, but the chickens found some and we couldn't get it away from them. Is that safe? They also like to eat deer blood. Wouldn't it be considered protein? What is your thoughts on the topic?
