Well, I'll tell you what I did, I too knew nothing about pigeons. First I read as many books as I could find on keeping pigeons, next I looked for a loft and stopped and asked the owner if he could give me some advice. I think that most fanciers are only too pleased to tell genuine people all about the hobby. Not only did I make a new friend that day, I also found a mentor who has generously given his time and shared his knowledge to help me get going with pigeons.
He found some good birds for me to buy in British Homing World (the fanciers weekly paper), helped me to build and equip a loft, breed the birds and then taught me how to train the birds to home.
Good luck.
