today I saw a bird that looked like hawk. my roos were warning the rest of flock like crazy and all of my chickens froze. I looked up and saw huge wings wide open that I have never seen before on the island. there were 2 megpies as well and one started to chase that strange bird and it turned and disappeared behind the hill. I got worried as I never close my coops and my chickens get up and go out as they wish. I heard that crows chase away hawks and just have looked in internet, megpies belong to the crows family. the island is full of them.
