I didn't know where else to post this.
It is a warning that if you see a flock of cockatoos coming down to feed with your free ranging hens, check them out very carefully.
I wondered what the cockatoo was doing to my silkie until I got up close and saw that it was a white Goshawk (had to look it up later in a book to find out what it actually was - I had never seen one before). It had absolutely no fear and only flew a couple of feet away, and settled, staring at me. It didn't move until I virtually went right up to it yelling and screaming!!
The info in the book says that they often hang around with groups of cockatoos as a form of camoflauge.
My poor silkie pullet - she didn't stand a chance.
So look twice, next time you see a cockatoo amongst your chooks.
Oh, and Goshawks are apparently a protected species - so no revenge possible.
