I'm curious what the return on investment cost is for various coops is. Use this formula
Coop Cost / (dozenEggsPerWeek* price) = number of weeks to break even
So my coop cost me about $200 to build. I'm getting three eggs a day so thats 21 eggs a week which is 1.75 dozen. If my local price I have been paying for eggs is $4, then I should break even in . . . 28 weeks (assuming I have free birds that eat nothing ;)
What's your situation?
