Schedule F and C profits are taxed at your ordinary tax rate, it's the additional 15.3% SE tax that applies to self employment profits over $400 that makes it heavily taxed. So yes!, be sure to deduct all of your qualifying expenses associated with your farm income, pasture rent, vet bills, feed purchased or raised. Also be sure to expense vehicle mileage and depreciate any breeding stock (purchased cows or bulls), buildings or machinery used in producing this farm income.
To my knowledge, no states require an EIN/tax ID # for a sole proprietorship but all states require one if you have employees. So unless you have employees you do not need an EIN.
