Wintering chickens actually seems like the least intimidating part of starting the farmstead.
Shelter- Hoop greenhouse over garden. One example is $100-$150 for a 9’x8′ structure. I can easily predator-proof it, provide deep bedding and lock the chickens in at night while letting them wander the garden by day fertilizing everything.
Feed – I am a big advocate of letting animals express their genes thus allowing them to alter their own diets to make up for deficiencies. I will provide them with basics. Carbohydrates will come from spent brewing grains and garden produce. Squash, sunflowers and Corn will be grown specifically as winter chicken feed as they both store well when harvested and handled correctly. Soil in the garden is rich with earthworms to provide protein (28% by composition) and fats while the worms are active. Additionally, red wiggler worms will be an integral part of the composting system and can be fed to the chickens. Honey locust pods are easily collected from the many trees in the pasture. The pods could also be collected for the goats winter feed. Persimmon trees are numerous and heavy producing, but are not as easily harvested.
Supplements- Keeping as much feed on-farm as possible, yeast will also be an abundant byproduct of my brewing operations. Enough yeast for subsequent batches of fermentation can be harvested when the current batch is complete leaving about 95% of it to go to waste. That wasted yeast is a great source of vitamins and minerals including calcium, the most important consideration for laying hens. To ensure all nutrient needs are met, I will provide some off farm sources to see if the chickens utilize them. These will most likely be kelp, oyster shell or other conventional sources.
Future considerations: Aquaponics to recycle processed chicken innards and waste as fish food as well as worms that feed on chicken droppings.
