When we first got our girls we kept a mental tally of how many dozens of eggs they'd have to lay to "pay us back".
We initially figured $3/doz was roughly the going rate for organic eggs in the grocery store but they've since gone up to $4+.
First store stop: = ~$15 (4 doz)
Birds + feed + pine shavings
Second store stop: = $8 (2 doz)
Heat lamp bulb
Third stop: = $6 (1.5 doz)
Clip-on lamp for bulb
Fourth stop: = $2 (.5 doz)
Canary grit
(about now I'm thinking, "this isn't so bad!")
Then DBF starts the coop...
Stops 5 through 52: = $300+ (75 doz)
Wood for coop, misc. hardware, chicken wire, feeder, waterer, staples for gun, cargo net, more pine shavings, more feed, big girl grit, more wood for coop because we ran out, more hardware because I'm paranoid about predators, stakes for chicken wire to go around garden because they're eating it, the jalapeno plants they ate, the beans they ate... ad infinitum
I'm sure we've spent more, but counting past 83 doz eggs ... oof! That's nearly 1000 eggs. If we get 10.5 eggs/week from our 3 standards (and take the bantam cochin out of the equation) we're looking at 94.86 weeks until the girls have laid enough eggs to earn their keep. That's only 2 years, right?
If they lay well.
If they don't eat another bite of feed!
So yeah... profit... hrm...
