Let me share with you my experience on two separate occasions. Last year that is the beginning of the 2007 season I lost one of my own Hens, and I could not find one any ware so I bought one from the local dealer, after the quarantine I tried to pair her up
with few different cock birds no luck, so I then let her in to a flight with all the others for her to select her own choice,
no luck again, after a lot of enquiries few months after, I found out that she come from a breeder who uses Bengalese as Foster Parents so that was that it went back to the dealer. The beginning of the breeding season of the 2008 I have one Black head Blue Back Hen with out the right partner, so my best friend offered me one of his Orange Head Yellow Back Split for Blue, I gracefully accepted, but after a five weeks having them together I noticed that there is something wrong with him he is not acting like all the other cock birds, and keeps to him self, and sleeps by him self, in a corner,
so I got back to my friend and found out that he bought few splits from a breeder in NSW, by getting his name explained everything, yes you guess is correct,
he is one of the unscrupulous, dishonest breeders of Foster Bred Gouldians
