Our birds free range and until recently we have had no issues. We live South East of Raleigh, North Carolina and have chickens, ducks, geese, turkeys, and guineas. They have access to several acres. We went to check on the birds the other morning and found the carcass if one of our 2 month old Buff Orps. It was picked clean. Head and feet were left, but were detached. The next morning, I found one of our year old Plymouth Barreds dead. Carcass ripped open, very little eaten, head and feet attached. Any idea as to what type of predator we are dealing with? Trying to figure out how to secure our birds as we have a lot invested in them. Since we travel 2 days a week for work, locking them up every night is not an option. We have put one of our guard llamas in with the birds for now and there have been no new deaths. Thank you in advance for any help or suggestions you are able to give.
