Walter, If the view is that today's feeds are responsible for increased losses in our pigeons I don't go along with it, today's feeds are far superior to what we were feeding 30/40 yrs. ago and the same applies to humans, there are many more oldies now than we've ever had. I think with our affluent society we keep many more birds than we used to and breed off them whereas our fathers and grand-fathers were much more selective in what they kept.
