I posted this in its own
thread, but given the better traffic here, I though I would repost. Here is a perspective on meat chickens that goes against the CX mindset-
I like slow-growing breeds for several reasons. Slow growing birds have lower daily
energy and protein requirements, so they are not nearly as dependent on processed and soy-based feeds. Their lower energy requirements allow them to make better use of low energy/ high nutrient food sources, such as what is readily available in a range setting. I am to raise my chickens in the context of 'natural farming', and slow growth makes this more realistic than breeds that were developed for rapid growth with factory feeds.
Mortality is much lower with birds that are growing slower, and are under less nutrient stress. Last year, we harvested 63 birds from 65 day old chicks. That low mortality is crucial for the commercial viability of our operation. Amortizing the costs of mortality, including the feed consumed before dying, is expensive. Plus, it sucks to deal with dead chickens on a regular basis.
Heritage breeds are like heirloom seeds, and we
should support these historical legacies. When small commercial farmers turn to the hatcheries for quadruple hybrid birds (Cornish Cross), we are telling the hatcheries that we dont care about heritage breeds. If only backyard enthusiasts purchare the heritage breeds, their stock will slowly degrade and we will be left with curiousities, not the historical workhorses that our ancestors developed. It is a cause worth supporting to keep our flocks biodiverse.
Slow growth means a long growing season, which happens to line up perfectly with the foraging resources of a temperate climate. We hatch chicks in mid-April in the
greenhouse. The environment there is protected and bursting with bugs and forage. By mid-May, we move the chicks to their field house. They are well-feathered, robust, and ready to make use of the bugs that are hatching outside. All summer long, from May-Sept, the chickens are ranging during the season of optimal life on the farm. The chickens are still around in the orchard in Spetember to clean up the dropped orchard fruit. The life cycle of slow growing chickens is perfectly timed to the cycle of life on our farm. Remember, chickens are workers on a
permaculture farm, and we work our chickens from last frost in spring up to the first hard freeze in fall. The whole farm organism benefits from this long life cycle.
The labor requirements of a five month grow-out are suprisingly similar to a shorter, more demanding grow cycle. Once our birds are three months old, they have 'gone pro' at being range chickens. They are perfectly trained to come home at night, large enough to withstand a hailstorm, and smart enough to avoid predators. All the work is getting the flock established.
At harvest time, we average over 5 pounds dressed carcasses per bird. The meat is dark and rich. The copious body fat is golden yellow. The birds are just on the brink of sexual development at 5 months, so we have maximized the natural life cycles of the chicken.
By now, you must be wondering, which breed? After years of experiment, I have settled on Black Jersey Giants. They are commercially available, heritage birds. They are smart but not devious. They grow large as a chicken can. The inexpensive assortment of hatchery meat chicks often is full of second rate meat breeds, like Aracaunas and Wyandottes, that never fill out a plump satisfying carcass before sexual maturity. The cheap choice is usually not the most economical, and that is certainly the case with meat chickens.
Finally, as the icing on the cake, the female Jersey Giants go on to lay quite well. So well, in fact, that we have taken to keeping a dozen hens and hatching out our own chicks this year. So the hatching of baby chicks is one more element in the cycle that we control and profit from. The vigor and vitality of home hatched chicks is something to behold! Such a joy to participate in. I'm raising a big, fat, fried heritage chicken leg to this system right now! Cheers!
