That is a very sad story. I never thought of my chickens eating stings! I will need to take a look around, I think the tarp over their shelter is fraying but I never would have dreamt that they would try and eat it.The sweet little wellie roo I posted about a while ago died. I had a tarp wrapped around my greenhouse where I was keeping them and the edge was frayed with strings coming off, and y'all know how wellies are, always so curious, he just snapped it right up. Judging by the autopsy I did one end of the string got wrapped around his tongue and the other end wrapped around the grass and food in his gullet. As the food passed through the string pulled tighter and tighter until it was bending his neck in an S-shape. He was still alive when I found him, I brought him in the house and put him in a pen, by then he was gasping for air, but I couldn't see the string to pull it out. A little while later he started going into convulsions, then literally died in my arms.
I am kind of sad about it, he was one of my faves, but at least I have another wellie roo for my girls.
Very sorry for your loss
