I wouldn't get pigeons from birdtrader as lot of them are scams. People put photos up of pigeons which are not even theirs (not blaming all sellers, but have heard from friends). That guy Azz is someone you should not go to. He sells a lot of rubbish pigeons. You are lucky if you get something good.
Pigeons from auctions are no good most of the time, they are peoples rejects. Unless its a pigeon club auction then different.
