Gone . . . but why? If she simply could not recover, and you did your best, then so be it.
But if your husband decided that he knew best, and killed her (call it "culling", or whatever euphemism you want; it is what it is), then it sounds to me like a spirited and loved bird who had a fighting chance was denied the opportunity to fight back and recover. And in my home that would lead to some serious discussion.
And I am the husband here.
Not trying to sound judgmental - maybe I am being so, regardless, and maybe I don't know all the facts - but it would be a hard thing.
We have been fortunate. In 2 years with our 4 hens, we have had one near miss when they were free ranging in the yard and a bald eagle nearly got our RIR/BuffOrp cross. We saw a swoop, heard a squawk, and found a spray of pinfeathers on the yard. Thought we had lost her for sure, and it was a pretty sad afternoon. But an hour or so later, I looked out and saw 4 birds huddled under the truck - and she was 100% OK! Must have barely dodged the bullet. Later, I had to chuckle at what was surely a PO'd eagle who missed out on a chicken dinner.
We are more careful now.... Raccoons and an occasional fox are, I think, the main concerns around here.
