Don't get me wrong i luv eyesign, But when i was very keen i would go down the loft one night every week lights off my then partner would put all the birds into a basket, i would then judge all bird by hand anything i didn't like would go into a basket, and judged again more often or not some of those in the basket had good eyes, but they needed to come to hand first before they was bred from, and my birds would would win out to 593mls so its not all in the eye,
Regards
