I am looking into starting a line of my own birds. I have three trios. I have read about two different types of breeding and I was wondering what you guys did! One is called Clan Mating and you keep different sets of birds and breed males from one set to females of another set (best I can understand). The other is one I got from another forum where you breed like this: "First Generation Hen Cock ½ hen ½ cock Second Generation Hen to son Cock to daughter ¾ hen ¾ cock Third Generation Hen to grandson Cock to granddaughter 7/8 hen 7/8 cock Fourth Generation Hen to grandson Cock to granddaughter 15/16 hen 15/16 cock Now in the 5th generation you breed the 15/16 hen to the 15/16 cock. Then, choosing the best hen(s) and cock(s) you begin again (Narragansett, The Gamecock, 1985, pp. 44-45)." http://ultimatefowl.wordpress.com/2009/02/11/line-breeding/ To sum it up... what do you guys do?
