2 questions concerning the safety of my girls.. first so you know;the run area has 8ft privacy fence all around and there is heavy guage wire connected and all across the top as well as under the ground,they can go in and out of the secured coop via a trap door.So.. #1 This am before I let them out there were squirrels running across the wire fencing on top on the run...Can squirrels hurt chickens? What can I do to keep them away? #2. We have had 2 or 3 red tailed and 2or 3 regular hawks flying around all day for the last 2-3 days.What other precautions should I take?? I believe the wire is 2inch squares..Ive not seen them swoop down,but they do get pretty close and just having them ard makes me nervous.There are 2 big plastic owls 1 abt 50 ft to the left n 1 abt 50ft to the right.(My neighbors have them in theyre yard) I appreciate any suggestions..The only one Ive read is abt the foil or Cd's hung above the fencing.We are trying to figure a way to do that as there are huge evergreens behind the fence and it is abt a 40x40 run..Thanks so much
