Super sad news guy

I came home from work just now only to find Quilliam didn't great me at the door of the aviary. He wasn't in any hides either, I had skirting all around the aviary and bricks buried along the inside for digging, but it turn out Quil had gotten distracted and stuck his head through the fence I assume for a bug or some such, but it appears that the Cooper was stalking the coop and grabbed him by the head trying to pull him through the fence

I don't know if I should be thankful the hawk couldn't take his body or not, I was able to bury him but now they'll just kill some other poor bird to feed their own family (there's a pair on our block) I'm going to try and surround the aviary whith cement blocks so the birds can't get their heads through, I have a hutch but I'll need to fix the bottom before it's secure I'm so sad, I'm just happy all my other Pigeons are ok and the chicks are all growing well
