Paying personal property taxes is a bite but compared with what we were paying in property taxes when we lived in IL, there is no comparison.  We smile and write the check.
 
I think it has to do with whether or not your property is considered agriculture/farmland for you to be able to write it off as a loss or profit on your income taxes along with depreciation of equipment such as tractors and implements. I was talking to our accountants secretary yesterday and she was rattling stuff off to me about a new form that has to be filled out this year concerning our equipment, tractors, etc, and is a one shot form, blah blah blah. I don't even try to understand it. If you are selling eggs in a large quantity or chickens as a business you to check into it though. A loss is a loss.
 
I find it funny that geese are not mentioned specifically although they do have a category called 'exotic birds'. Geese exotic? Nah. I wouldn't consider quail exotic either although maybe peacocks and guineas fall into that category.
