You need to speak with an accountant who is familiar with YOUR STATE business codes, preferably also has experience with farming issues. Keep meticulous records of all of your expenses: Egg cartons, coop build, tools to build the coop, coop bedding, tools to manage coop and run bedding, fencing, building materials, advertising. Are you selling garden produce? Include the cost of your seed, fertilizer, insecticide, tools, grow lights, electricity for the same. Got a LGD? Perhaps you can deduct the cost of dog food and vet bills.
Then, there's the gas: every time you take a trip to town to pick up ANYTHING that will be used for your homestead, keep track of the mileage.
Liability insurance would also be deductible.
It would not be unreasonable to expect that you will actually show a loss each year! Farming is a good way to go broke while having fun and getting exercise.
