Hi guys, I’ve been a member here before but my old email is inactive so I have to start over. 
I’ve had chickens for 7 years. I’ve had them in a small area, and as of last year I fenced off a larger area in my yard so they have more room.
Apparently this year it has attracted predators. I’ve lost two chickens in a month. Seems to be at dusk. Without getting into the gruesome details, I feel like it may be a bird of prey going after them. There is no evidence of a dog getting in, unless something is climbing over the fence, I see no evidence. The coop area is narrow and always hoped that made it safe.
Both seem to be attacked near the coop as they were going in for the night.
Im traumatized by it!
The obvious solution is netting and locking them back down into a smaller area.
i guess I’m just wondering if there is any advice out there as to what you think it may be and how to keep them out of the area so my chickens can roam. If I can’t, I can’t.
Thanks for reading.
