Some poultry breeders use Line Breeding with their chickens. A more complicated, yet more effective way to line breed is to Spiral Breed. To do this, maintain three lines - Line A, Line B, Line C.
2 For Season 1, mate all males to females of their own line. Daughters of Season 1 are added as breeders to the line that produced them (they stay with their mothers.) Sons are compared to their fathers for quality.
3 In Season 2, mate the C line male to the B line females, mate the B line male to the A line females, mate the A line male to the C line females - rotating them.
4 Females from Season 2 are added to the line that produced them alongside their mothers. The best son of the C line male mated to the B line females is kept and mated to the B line females; same for other matings, old cocks are retired.
