She is a Terrier Mix and I get on to her all the time for barking at them, well tonight she tore through my Juvie pen! Killed a Splash Cochin Hen , Maimed a Blue Cochin and my Little Splash Bantam Rooster The worse part is I don't feel right saying anything to them as last week one of our pine trees fell and landed on top of the doghouse with their other dog in it Yep, he's dead! I have the 2 live ones in the house and will put up hotwire around the pen tomorrow. I screamed at her and she has not cme back over here since. Pumpkinpup came over and we cleaned the boys wounds and gave them some penicillen. I hope they will be ok. They also had some Poly Vi Sol and I mixed some Vitamins & Electrolytes in some water and they did each take a drink.
