ok,jack it is,but,i was allways told to mind my manners and respect my elders,,,,,,,,,anyway,i was never told that way,,,,,,,so,for eg;if i have say 20 pigeons that are all bull eyed,it would be a hit and miss affair to match pearl with yellow eye? the reason i ask is; i have 2 prs of white logaa ns,only one of them,cock bird,carries a pearl,as i only want whites and to make sure of breeding by your eyesign method,i must bring in a coloured pigeon with yellow and breed back for good eye pigeon,does this make sense?
