A Case for “Closed” Genetics in Yard Birds

From the onset of our layer operation we planned to implement a concept that Polyface Farms had employed with the genetics of their forage-based rabbits; line breeding, or “closed” genetics.

The concept is rather simple and straight forward… begin with a specific population of animals and do not allow any outside genetics to enter that population. The objective is to produce over multiple generations a farm-specific breed which is hearty, highly productive and carries particular strengths against the bacteria, parasites, diseases, climate and predation of the micro-environment that makes up our farm. It is an expensive experiment in that one has to allow nature to do her culling in order to find where those strengths lie within the population.

For our egg production we began with 225 birds (200 hens and 25 roosters). We purchased seven heritage breeds of chicken. We were looking for specific traits to impart within the flock, namely heat tolerance (after all our farm is in North Texas) and laying rates. We wanted breeds capable of producing 300 eggs a year. We chose: Rhode Island Red, Speckled Sussex, Black & Gold Sex Link, Buff Orphington, White Leghorn and Black Australorp. These represented the first generation of our egg layers, after which we closed the door to any new outside genetics.

Over the first 18 months we experienced the expected higher losses, losing close to 50% of our flock. Some of the loss was attributed to our learning curve and management practices. We have always had small backyard flocks, but there are plenty of new dynamics with a larger flock. We also lost some to predators, but this is also part of the process… one bird leaves the coop looking up while another leaves looking down. The hawks take advantage of this weakness. For the record, we do attempt to protect our flock from every predator we can, but nevertheless, this natural loss does serve to refine the flock and naturally reduces a population through attrition of weaknesses.

 

 

We are now on our third generation of birds. Our hatch rates are up to 85% and in our latest generation we have had a mortality rate of 0%. Albeit, the birds are only 2 weeks old, but they are proving to be hearty in every way. They were running within just a few days, sparring, flying and roosting on our lower nesting box roosts within a week. They have a vigor, strength and pep we have not seen in any of our previous generations.

In order to keep up with egg demand we have now consolidated all of our laying birds into a larger operation. This new operation is in essence a farm within our farm owned by Hunter Carter, affectionately dubbed “Hunter’s Huevos“. This operation will be able to grow up to 600 birds and supply Cartermere with 35-40 dozen eggs per day. The only genetic factor yet to be seen is our laying rates. We are currently at 57%, however this is not too bad for the heat of our summer months, and we currently have a number of pullets still beginning to lay so rates continue to tick up each day.

Through this process, in 10 years we hope to have a fairly standardized “mutt” layer which is a heavy producer and extremely hearty for our farm. We’ll provide an update in a couple of years on our progress.

On the Farm with the Chefs

Yesterday we were privileged to have a group of chefs and cooks out to the farm from CBD Provisions and the Joule Hotel Banquets. Everyone got their hands a little dirty with a number of chores.

After taking a short tour of the farm, we harvested mixed summer squash, zucchini and pickling cucumbers.

Everyone took part in our weekly chicken processing as well. From kill, to scalder and de-feathering, evisceration and washing. This activity was important for both the farm as well as the chefs and cooks, because Cartermere is currently supplying CBD Provisions with aged roosters for a special “coq au vin” dish. It’s important for the kitchen to know how the birds are prepared at the farm, as well for us at the farm to understand if there are any aspects in our processing that impact the end result at the restaurant.

After the work was completed the chefs and cooks did what they do best. Everyone came together and prepared a wonderful lunch. We had grilled Cartermere grass-fed lamb, mixed potatoes and onions, sauteed summer squash and a spectacular cucumber and heirloom tomato salad.

We also open a few Cartermere Farms’ pickle jars to get the chef’s opinions on this year’s “vintage”, and finished the day with a round of homemade limoncello which we make here at the farm for friends and family.

All and all, a great day at the farm! This is why we love the restaurants with whom we work.

Thank you guys for coming out and experiencing what we do. It was a pleasure to get to know you all better.
