thanks mate very interesting last year i paired the old cock to a good hen last year knowing that he didn't fill any eggs the year before, but the hen i paired him to was previously paired to our number 1 stock cock, as i knew that the old cock may not of filled his eggs, so till the 1st egg was laid i let the hen go in the spare section with her previous cock for a hour every day (but i never saw him tred her, i not saying he didnt) the 2 eggs were filled but both were cheq the hen is a blue and her previous cock was a blue the old cock is a dark i will never know if the old cock is the sire of the 2 yb but i do know that in the summer he did fill a egg and was a cheq a spit of one of the others
