A fox. It had gotten into the chicken's pen. It jumped our two layers of fencing and found a hole in our hawk netting. Hazel was killed. Julie and Ceci where too far gone. (Sunny was killed last year but, that is a story for another time).
They stole my heart in the four years we had together. I do not know what I will do without chickens. Luckily, the chicks will be hatching in about exactly a month. I loved those chickens more than I ever thought I would or could.
