My 8-month old easter egger recently laid two eggs within an 8-hour span, and then she died 14 hours later. She had never laid two eggs before, seemed very healthy, and had recently been moved into our basement while the temps outside were below zero. We only had two hens left, and now we're down to the last one. She is actually perched on the back of my chair right now, watching me type. She seems to miss her companion, and we are afraid that whatever caused the other's death may repeat itself. Can anyone help?
