I brought my almost 2 week old chicks outside today because it was such a nice day. The coop/run is still a work in progress so there is no top cover on the run yet. I was sitting out there with them and my 2 boys when I heard a hawk. Another hawk answered and I looked up to see two hawks circling. I shooed the chicks under the coop to get them out of sight, but when I looked up again, one by one, three more hawks started circling. I was beginning to think it wasn't a coincidence, so we gathered up the chicks and brought them back inside. The run is about 8' X 16' and the 3 of us were sitting right next to the chicks. Would a hawk really attack with a human sitting by? I didn't want to take any chances, but I'd like to know for future reference as I hope to let the chickens run around the yard (we've got about 2 acres fenced)sometimes with us out there when they are grown.
