How nice that your hens didn’t get harmed! I came home just yesterday to find a huge halk on the ground feasting on my 4-week ole Brahma chick, the other chicks scared to death. We let them “freerangw” in the fenced in yard and there is plenty of bushes and vines creating a very nice cover... plus we have an outside cat next to the chicks. And it’s still hot out here in Ca, and so never saw hawks here, so thought it was safe :’( But none of that helped. So now I ordered the same aviary netting, except since it’s our yard, we kinda do want other birds to visit ... so I haven’t put it up due to these concerns. Hope we figure it out soon, but for now we leave our dog outside to watch over the babies...
