So sorry about your loss.
My SO is weaving a top to his giant run with rope. After a super close call with a hawk, did not get chicken who was in shock for 30 min and is fine now. He thought she was dead. 2 days later - 6 hawks in the trees...just awatching. We thought they had enough cover. We think too much.
I have a covered run and a baby monitor, for when they are out. Maybe I could cover the whole yard with a net also...
I am kind of liking the golf or batting cage type netting for a smaller area.
Hope that's the last of the predator problems for you.
