Assuming that you have 3 good cocks and 3 good hens, the beauty of Walter’s system is that you can pair up your stock birds on or about 1st December and you would be ringing your first six youngsters on, or around, 5th/6th January. Your 11th and 12th youngsters would be weaned off, on or around, 21st April. Therefore, you would be able to get, at the least, 2 months’ worth of darkening for your 3rd round of youngsters. From these 6 stock birds, you could produce 36 youngsters of good or reasonable quality. The advantages/disadvantages if you employed the bull system (compared to Walter’s system) are that you would have to have 9 pairs to reach the same goal. Your best cock would father 20 young birds (2 each from the 9 hens and a further 2 from his own hen). Your 2nd and 3rd best cocks would father 2 youngsters each and the other 6 cocks would father 12 youngsters, making a total of 36 birds, and having the 2nd round weaned off on, or around, 27th February. Of course you could start again with the bull system after the 2nd round and your best cock fathering a further 18 youngsters and still have enough time to carry out the dark system. This way you would have 54 youngsters but get to test out more of your youngsters and stock cocks and hens. Six-and-two-threes I think Walter, I may be looking at both systems the wrong way but what do other people think?
