Quote: I was thinking of calculating the costs, but since I don't have exact numbers on the cost of the coop build I decided against it. Probably better that way. I guestimated about 1000 euros in so far, calculating with organic eggs, which is what I buy if we need to, I calculate we'll break even in about 20 months, not taking feed into account. Or the fact that our eggs are a lot smaller. Or the fact that I don't think we really spent 600 euros on eggs per year. But in reality, I think a bit over 2 years will be pretty much close enough to the truth. Not that bad really.
Oh, and what you need to factor in is that by composting the poop and bedding, you get free soil and fertilizer for your garden, leading to a better yield. More columns to add.
