Last May I became a chicken owner when I successfully hatched two silkie chicks with my third grade class. In July I increased my flock to six with the addition of four mail ordered silkie chicks. While I was raising the chicks indoors and after I moved my wonderful pets outside to their new home I constantly read information on this site. I read everything I could on preditor proofing and I thought I had made my pen as sound as Fort Knox. This morning my nine year-old came running to me as I was about to leave for school. Something had gotten into the pen during the night and had eaten the head off of one of the younger chickens. He was devistated. There were no holes dug under the fence (wire is underneath). The chicken was found underneath the chicken coop. What preditor could have done this? I really need your help. You guys all know what I'm talking about. These pets are like family.
