If he's topped the federation and a multiple scorer and so is his siblings, I'd personally breed around this cock. I'd pair him to the absolute best if you say you have three stock hens that have bred fed winners in my opinion he'd go with them. However if you haven't got what you feel is equal quality in your race team, you will have to weigh up the odds as there's no quareentee he will be a breeder of quality birds, and you cannot burn the candle at both ends. I can only state what we do hear and it's using this process, we like fast maturing young birds. We house 10 pairs of Stock cocks and only actual 4 stock hens, we take the best young hens each year from our young bird team and they are paired to our Best Stock cocks. Consequently we like to pair Uncle to Neice we find this pairing successful. But we also house two families of birds here the Frank Taskers and the Gevaert Van Schoorise. So we also like crossings. Interestingly both families way back in the line go back to the same family of birds the Andre Diereck birds. But Franks family of birds are a series of crossings.
