Eggonomics

We just finished out first 50lb bag of chicken feed. To date, we've collected 92 good eggs, and had 5 bad eggs laid. 97 total. So if you'll allow me a little creative license, assume that the last bit of food from bag #1 went into the feeder today, and that will provide us with 3 eggs tomorrow. Which means egg-actly 100 eggs from a 50 lb bag of food.

What	Cost
Coop	$250.00
Feeder	$20.00
Food (50lb)	$13.00
Oyster Shells (50lb)	$15.00
Hens (3)	$23.16
Food buckets	$16.00
Pickle Jar for Water	$5.00
Shavings container	$6.00
Food (50lb)	$18.00
Total	$366.16

So if you assume $18 for a bag of chicken feed, and label every other costs as fixed, our ongoing cost for an egg is $0.18, or $2.16/dozen. Not bad, though it does require that you ignore startup costs, and peg our labour at $0/hour.
