I am fearful for my remaining hens cause the cause for sudden death is unknown. Every time I go outside where they are I hold my breath until I see they are all alive and well. It's going to take some time for me to get over this. Sorry for your loss too. I share your painSorry for your lossWe lost one of our easter eggers last week too. She was about 3 years old and perfectly healthy. Acting completely normal the day before. But when my daughter went out to feed them the next morning she was dead in the coop.
No damage or obvious stress. She looked like she settled down for a nap and never woke up. Her sister and the other chickens are still completely fine. The only thing we can take solace in is that she passed peacefully without stress or fear.
