Personally I would never tolerate or even want o breed or race a bird with any wrong traits , it's bad enought trying to get near perfect types to score at the distance , doesn't mean it won't be a bad bird but, but breeding a hut fll of fancy colours also had its drawbacks , I suppose that's the difference between us bak door fanciers ,and master strain makers they have very high standards ,Stan biss ,alf baker , Alfred Bennett to name afew come to mind and recently mr and mrs Elliot , onwards and upwards ,😳
