I think you have the chicken math solution backward my friend.
Read the above and said that sounds familiar--started with 6, max 34, now 28. I thought chicken math is what we men do with a slide rule and a tractor to estimate how many chickens she will eventually get/want and try to stay ahead of that estimate with proper coop/fence/yard/storage size to outpace her chicken rusings in the future...
The FEL sure works better than a wheelbarrow for coop cleaning, carrying to burn pile or spreading out in the woods.
She: Money can't buy happiness, but money can buy chickens, and chickens make her happy.
Us: Money can't buy happiness, but money can buy a tractor and more tractor stuff, and using said tractor for her chicken stuff makes her happy, and THAT makes us happy.
