My grandmother was a wise woman. She used to say "consider the source".I doubt I'll ever know any more. The person who sent me the email is the most contemptible person I have had the misfortune of knowing and nothing they write can be fully believed so any further information is unlikely.
How some 25 healthiest, breeding chickens can have been wiped out in around four years doesn't bear thinking about.
Some people revel in causing misery, but I try to just ignore them. I prefer to surround myself with others who aren't that way. Including animals.
