Sudden turkey death.. need your ideas

[princessferf]

I have 10 turkeys and about 20 laying chickens.  They share a coop at night, during the day everyone free ranges.

Everyone has been doing great.

This morning I discovered one of my turkey toms dead.  A group of its breast feathers were pulled out, but no additional trauma.  Of the 10 turkeys, 3 of them are toms.  Now I'm down to 2 toms.  

They tom who died was totally fine yesterday.  The group of turkeys are about 1 month away from butchering.

I'm not seeing signs of blackhead and their stools are normal (albeit giant!).

Thoughts?

Questions....
Where were the loose feathers in relation to the body ?
Was any of the meat missing from where the feathers were out ?
Any trauma to the head and, or neck ?

My thinking going towards great horned owl, eagle or such. A mature eagle is more easily identified, a jeuvenile eagle can easily be mistaken for other birds.

Those two birds are the biggest problem our feathered livestock has.
