i know of people giving this to combat young bird sickness and they swear by it for this illness and are 100% certain in saying it works. And they are old established fanciers .
If somebody did sell it they would be rich, but would be impossible to keep all the birds , you dont want to lose them , but it is a fact that is what happens when you race them, unfortunately they will get lost sooner or later.
Was there a man in Lanarkshire named Harwood who kept his birds in almost completely open lofts with wire all round, were his birds kept in these nearly all year round and raced to the open style lofts? did he ever have many health problems with his birds ?,
