After getting into chicken raising, I still can't get over how comically cheap the chicken itself is compared to everything else that goes into their care. In total, I've put like $40 into live chicks, but well over $1000 between food, shelter and other incidentals. Not even including the blood, sweat and tears that I spent to build all the stuff. Chickens are a lot of work, but very rewarding.
This.
One year and a couple of days into keeping chickens:
$60 for the chicks (bought 11; kept 5)
$150 for feed
$20 for oyster shell
$10 for grit
$30 for pine shavings (most of the bedding has been free for the labor of picking it up off the lawn)
$10 for sand
$30 for PDZ
$10 for waterers (at goodwill)
$40 for winterizing the waterer so the neighbor could do chores once per day for a week in December in cold climate
$20 for feed pans
$30 for 5 gallon pails, simple lids, gamma lids
$5 for fungus medicine
$10,000+ for the shed (probably get $4,000 back in increased resale value as a lawn/garden shed) - the building itself, delivered, then modifications like shingles, ridge vents, paint, hardware cloth, ect.
That is what I actually spent, not counting the cost of driving to get anything. and not counting things I had laying around or otherwise didn't pay cash for (more 5 gallon pails, crates for nests, locks for the door, greens and bugs, some sand, tub for dust baths, some of the screws, etc)
Next year should be just feed and $5 for a 55 gallon barrel for feed storage experiment. Everything else should last through at least a few years.... even the consumables like oyster shell.
I forgot the puppy pads, chick feeder, chick waterer, wool for the wool hen from goodwill for when they were babies - $30, maybe.
