On another poultry forum I frequent a trained geneticist recently wrote...
Do keep in mind that males contribute as much to diversity as females. If you restrict your male numbers too much, it doesn't matter how many females you keep. Effective population size (Ne) is a measure of diversity that includes numbers, relatedness, and gender balance, and is used in breeding programs for some species. If you apply it to small chook flocks, you get some interesting things. The offspring population from one male and 1000 females (or 10,000 females) has an Ne of slightly less than 4. The offspring population from two males and 2 females has an Ne of 4. (These calculations assume equal reproductive success among hens, and among roosters. Without equal success, Ne will drop somewhat).
Paraphrased, a flock of 1000 hens and one cock has the potential to produce as much genetic diversity in their chicks as a flock of two hens and two cocks
....cool, eh
it's something I've been contemplating a lot lately, that and how undervalued males are in poultry world in general.
Pair mating IS a lot of extra work, but well worth it in the end imo....especially when you're just getting started working with a new strain. Knowing who is producing what is vital to making any kind of progress forward. And good record keeping is essential, as is having a game plan. I used to think I could remember everything of importance, but soon learned I was sorely mistaken in that. lol Now I like that I can grab any bird in my flock, read their toe punch, and know their exact parentage and/or matriarchal line.
DeWayne, I do the same thing. One thing that made my pair matings a bit easier (and speedier) this season was the use of food colouring. A few drops in the vent of a hen for a few nights in a row, and any eggs laid in the next week or more will be faintly streaked with colour, making id a breeze. I used four colours; red, blue, green and yellow on individuals that were housed together and rotated cocks in. That way I could keep the small groups together (I find the birds are happiest and healthiest when kept in small, mobile flocks) and could still pedigree mate. Worked like a charm...minus my colour stained fingers.
