I lived in Welwyn Garden City, Hertfordshire. I haven't got the birds with me neither with Rodney. The birds are still housed in his friends loft who passed away. If you ring Rodney then he would be telling you about the birds. I think he still have to pick up the birds from his friends loft prior to letting it go and you have to arrange a courrier if you want some birds. Hope this help. Thank you very much and have a nice evening.
