Haha, I know how you feel! Well, I am not completely certain of this one: But once, there were lots of Bologna strings in our gully (we had thrown some old bologna out and didn't even think to take the strings off with dogs, cats, and chickens!

)
Well, the hens began foraging near them and when we check all of the bologna- strings and all-were gone. So don't feel too terrible on that one.
One winter, (it had snowed and the girls had been cooped up for days on end) and I had put a Styrofoam bowl to hold some treats in; and the girls had eaten quite a bit of that

But they all lived.
And they have all had a mouthful of pine shavings at one point, so don't feel so bad
