It's supply and demand really.
Phoning Brian will not be a problem he is a really nice guy.
I had birds from him 10 years ago slightly different breeding from what he is timing now but one of them was £250 at that time.
He has had an advert in the BHW year book every year for many years now. I think it serves little purpose now as the birds will sell on his performances. His advert is only supporting the BHW.
