I am so terribly sorry for your loss, Amanda. I can see that Snowball was a very special hen to you, who came into your life at the time when you needed comfort, and she gave it to you.
You are obviously such a caring person. You have an animal sanctuary. You take in chickens who are disabled. you feed them organic veggies and provide clean water and a good, stable environment.
I'm so sorry this happened to you. Sudden Chicken Death Syndrome is truly a terrible thing to happen.
I hope your husband is recovered, and my thoughts are with you.
