It's always sad when a chicken dies after you've put your heart and soul into trying to save it ): Sorry to hear, I hope that none of the others are affected!
i am so sorry for you!! i know i would be devestated if something happen to any 3 of my girls. i know non chicken friends dont understand. people tell me alot they are CHICKENS. i know they are but i love them very much. they are special to me.
