Get your taxes done using TurboTax

If you are using TT premier online, you will need to upgrade to Self Employed to get schedule F support.

Your breeding stock is entered as a business asset much the same as a tractor would be. In TT, there is a category specifically for breeding stock.

The cost of feed is an expense and entered in the year they were paid.

The loss of 5 lambs is just that. 5 less lambs to sell, there is no other entry in TT for a loss of raised farm products because you expensed the cost of raising them.
