dont know what its like in your area billy but up here if your left with half the birds you breed at the end of the season you have done well m8 would think it will be the same where you are if your racing natural just give the eggs a good shake when there about 5 days old then let the birds sit them till they desert the nest and start to go to nest again this way you keep the incentive in the birds and you can always slip a youngster or chipping egg off your stock birds under them when you want more effort from them good luck with it m8 with a small team dont try to compete with the bigger team men choose your races and you will get your turn if you have done your job and your birds are good enough atb
