This morning there was a Cooper Hawk (I'm almost positive) on the top beem of the run! I only have it covered with cheep black netting. We are moving so I don't want to change it. Will it try to get through the netting. WIll it get tagled and frustrated and go away? Will is get tangled and fall into the run???? AGAIN!!! How dangerous is a Cooper Hawk to full grown full sized chickens?
