I found pieces of broken glass and small pieces of plastic in my little Cochin's gizzard. Her life was cut tragically short by our dog. My poor kids are devastated! She is the first chicken I have ever processed. I am planning on getting meat chickens this spring so I figured I better get some practice. I have had all of my chickens since last fall and they all appear to be in fine health. But it made me worry about the rest of them when I saw all the glass. I guess it is kind of like them eating pebbles. I'm just so glad that it didn't do any damage but I have no experience if there is a potential to do some really bad internal damage. I have also seen my chickens gobbling up pecked at Styrofoam. Does any one have any ideas?
