I don't think decrying the eyesign theory to the lowest of the low is necessary.Even if there is no scientific weight to it,its a great conversation piece for many fanciers and some will enjoy many hours studying the eyes of birds be it their own or various other champions.Theres more to keeping racing pigeons than winning races. I'm ignorant to it and would not know what to look for regarding signs.I was handed an eyeglass recently and didn't know how to use.I do however think there is something to be learnt from looking into pigeons eyes,not neccessary from the "sign" point of view but on visiting a couple of top long distance fanciers they have lead me onto a thing they call "family eye".This is not looking for a sign to determine whether or not this bird will breed winners,this bird will win etc etc. but these fancier have worked with their line of birds for nearly half a century and today's winners are related in someway to yesterday's.So basically they look for characteristics in their young hopefuls that were present in their past winners,the eye being one.I've been quite amazed at the similarities when looking at photos of recent winning birds and their eyes compared to those of their ancestors.
