Cheer's,
I'd be into doing that I've a bird table out my back and I've put a few feeders around the housing estate I live in and get plenty of bird visiting them,I must look to see if they do something like that over here.
Im in two mind's to get a small box and and put it on the fence and get a pair,I remember when I was a kid we had an old fridge out the back and I kept a pair in the freezer part for months before I got a loft built for them.
Yeah Neill from what I remember him saying that he let's them out to bring in the racer's but I didn't really get into it with him because I'd end up getting the goo for some and end up with 50 of the cnuts haha,I've kept Tumbler's on and off all my life I'd love to have some but my back garden is only the size of my kitchen and I just don't have the room but I'm hoping to move in the next year or two then I'm getting the young lad a few pair's of Tumbler's.
A friend of mine had some the last time I talked to him I think he used them to bring in his racing pigeons I'm sure he'd give me a couple if you want more or need an extra hen or cock.
