so much to read - yes, I did read it - amazing - have never met a human with that condition, but my taxi-driver friend in Vienna has, and he shares a lot of information - too much for here.  I am guessing chickens don't get psychological problems . . . .
any thoughts on why this happens?
P.S.  what I/we did notice when we kept chickens way back in history whilst living in the country - that they are not at all nice and will find the weaker ones and pick on them, literally peck them to death, if not stopped.  Ours had lots of room, used to let them out of the run etc.
