There is some animal coming into our barn overnight! We have lost 26 chickens 8 ducks and even 5 guinea fowl in the last 3 weeks! A friend told us that windchimes would make the animal nervous and scare it off. Does anyone know if this is effective or have any advice? Our barn is open and our critters run free with the exception of the goats, but the attacks have only happened in the barn. The six chickens we have left now roost outside trying to be safe. I have even waited outside to try to get rid of whatever this is, but never showed. I am really confused as to what would corner the birds and kill them then drag them out of the barn to eat them.
