Is that normal for a chicken to just drop dead!! WTH... Should I cull them all? I have no clue what happened? And start fresh? Oh I'm going to need some new ladies if anyone has brown/white, large egg layers... Awe man....
It happens. It could have been any # of things. From Heart to Tumor and anywhere in between. I wouldn't cull if there weren't any warning signs. I don't know of any disease that just kills a chicken overnight without some kind of warning signal. Of course I'm no expert either.
