It's the penalty for me letting birds free range here. Most of the silkies stay within 10 feet of their coop. That silkie cockerel is very good at watching the sky and giving warning before anyone else.
So sorry for your loss, I lost a chick too a few weeks ago. I guess it was to a hawk too, maybe even the same one... (I'm your neighbor in Eatonville!)
I choose to let my birds out and free range too. Its a risk I choose to make for their enjoyment.
