Howdy neighbor! SC here too! I've learned so much! My new favorite thing during my 'me' time is to check BYC on the old iPhone while I watch the chickens.
Yes I do believe it was a human. Found an add on Craigslist for some chickens for sale (pictures included) and it looked exactly like my babies! Emailed them with interest but got no response. It is sad that someone would be so cruel, two of those stolen were pets.....not just livestock with a purpose. Harley was my baby. He would follow me around in the yard and sit by my feet on the porch, et outta my hands and was so very gentle with my daughter. Very comical, those two were. He would chase her and she would chase him. Miss him dearly
