Our meaties are 5 weeks today. So far it's been good. Out of the 104 they shipped one was doa and we have lost no other until today. This evening when we went out to fill their feeders one was flipped on it's back. We picked it up and it was convulsing and died within a minute. Does anyone know what may have caused this? I don't have the time to open it up but if need be, may be able to do so tomorrow.
