I'm not going to engage in a piss fest with you. I'm relatively new to BYC, but my short experience here has shown me that people share what they know by experience to help others. What one person experiences may well be different than what others experience...but the sharing of those experiences just may help someone. You may link articles from England about animal behavior and whatnot, but not all animals behave the same in every area. A person isn't spreading "lies" because they shared a personal experience with a particular animal in their locale...it's just a different experience.
My heart goes out to the OP and his wife on such a devastating loss and if any of my experience with wildlife can help them in anyway, I feel it's only right to share what I know. I knew nothing of chickens prior to my rescuing my flock but the nice people here certainly helped me.
I will bow out of this thread and wish the OP the best wishes for closure and a new beginning...
