Glad this thread is here. I've been discussing with my neighbor about this very issue. They gave up on chickens because of the predator situation. If it wasn't areal, there was a fox hanging round. I have a 'predator proofing' plan in place for when we build the coop and run this weekend but I will now be adding the Cds as well. We chose BOs because they are a larger breed. We assumed that a chicken that size might be less appealing to hawks but I'm guessing that was a silly assumption? We also have Coyotes that roam the area and have been known to get pretty close to our house.
