Well I just got off the phone with Texas A&M diagnostics lab - I had sent in a hen that died after having some sort of respiratory issue. I have been stressing and obsessing over whether or not my flock has MG since they got sick with some sort of respiratory illness last winter and I was unable to send one for necropsy. I was able to do it this time thought and I sent my dead hen off for a necropsy yesterday. They determined she inhaled crumbles which lodged in her wind pipe and asphyxiated her. I am just sharing my story because I feed an all flock crumble and never thought something like this would happen. He said it does not happen often, but it does happen more than you think. I am not saying stop feeding crumble, but I did want more people to be aware that there is a risk of your chickens asphyxiating on crumble! Maybe this will save the life of someone else's chickens. RIP Lady Gaga. You were beautiful. You were fabulous. But you ate like a pig. You will be missed!
