I've read Bob's posts and articles where he says that a trio will get you about 5 years of good breeding without needing new blood refresh the gene pool, so I'm wondering what you're getting for the $500-$600 that will last a life-time. If $300 gets you a sound trio, does $600 get you 2 trios, or 1 really good top of the line trio?
Well, pricing is hard to say. A sound trio that is not a sibling mating should get you at least five years. Starting with three or four pairs can get you very far, indeed. You just keep their pedigree and control your matings. If you start with two pair, you'll go far. It would be nice to have someone in the same boat with you. Bob mentions it a lot, but having a partner is great. Every so many years, you can exchange cockerels.
When buying a trio, how far removed from the cockerl should the hens be? Surely not brother-sister. But what about cousins? Aunt-nephew? Uncle-neice? 2nd cousins? Or, grandpas cousins great grand-daugher twice removed?
Don't buy sibling matings. Don't buy from anyone who can't tell you whether or not it's a sibling mating. There are all sorts of possible permutations. The breeder selling to you should be able to explain to you where they are and where you'd be better off going with them.
What about the hens? Could they be sisters? Or would you prefer something else?
Sure, the assumption is that you're going to map out your matings, and you can do a lot with birds from one clan. The question is whether or not you're going to be totally self-contained or not, i.e. whether you're going to have a partner, or a community connection or not. Being totally self-contained requires a modicum of numbers. A lot of people don't want to have that many spaces and coops, etc... In such a case, I wouldn't recommend going for the rarest of the rare. If you start out with Silver Pencilled Hamburgs but only want to maintain two cock-birds, you're asking for trouble down the road, but if you go for Brown Leghorns and only want to keep two cocks, you'll be fine.
How far removed should 2 trios be?
On a side note, 3 15-22week old started pullets from Murray is about $20ea, shipping is $100. So you're $160 in to get juvenile hatchery stock(without a rooster). Seems to me that to pay $200, will get you quality just above hatchery. Maybe at $300, you're starting to get somewhere. By the time you consider tagging, hard culling, time, feed, etc., $300 sounds like a steal and $400-$500 gets you something worth breeding.
Indeed, I think that few breeders actually ask what their stock deserves.
Keep in mind, I only have hatchery stock right now, but my SOP is on the way and I just subscribed to the Poultry Press. That's $100 just to start learning about SOP chickens.
Bravo! And you're going to do great. Have you started attending shows? What are you hoping to do breed wise?
Most of all, stay open, which it sounds like you are--buying your standard is a good sign. So very much about what I know is the inheritance of reading and mentoring--doing what I'm told. So often I'm with somebody who has it all figured out, and I can't tell them anything. They tell me what they're up to, and I know they're going to crash and burn. So often, if I try to say something, they just try to further justify what they're doing. What good it that? If a breeder you know from the shows, who seems well connected, and intent on getting things right is telling you you're heading for a stone wall, put on the breaks. Stay open to change and program adjustment.
I'm telling you what, we talk about individual breeders--maybe. I know that's not my case. These birds keep getting better, and I can say truly that it's a work of collaboration. Yes, I pay the grain bill and shovel the bedding, but every year poultry friends and judges make the tour, check it out, tell me what they think is good, voice their opinion on where they think I should go. At the shows it's, of course, more of the same. I constantly have a little notebook in my back pocket so that anything the old breeders and judges drop gets scribbled down as quick as I can. I volunteer to clerk with every chance I get. I admittedly corner judges and breeders, whatever they're doing, I want to watch. Even if it's about a seemingly completely different breed, they're going drop a ton of info that with a little tweeking can be transcontextualized into a scenario that will advance my breeding programs.
Once you decide on a breed and variety, now's the time to start shopping for the fall. You want to set your purchase up ahead of time and not come sliding into home at the last moment.
Best of luck!
