I just got a GSD puppy about 3-4 weeks ago. Hes causing SO much trouble with my chickens. Hes torn up 3. Ate one silkie (who had been pecked real bad by the other chickens) Tearing up one hen (who died in the night from fowl pox down the throat) and this morning I let him out went to the bathroom made my kids breakfast then I hear my big GSD barking up a storm I go out there and shes jumping at the puppy so I run down there and hes torn the feathers and his tail bone off! The chicks anus is all bloody opened up and pulsing. I doubt hell make it. I beat the snot out of the puppy while he was doing it but Ive done that the other two times (while he was tearing up the chickens). I just dont know WHAT to do! Please tell me there is hope! I think its just because hes a puppy but I dont want this to carry over into adult hood. Neither of my other dogs mess with them! In fact my big GSD was trying to protect the chicken he was attacking. How do I stop this?!?!
