I do not understand the mathematics behind the dilemma. I'm assuming only the firts chicks cost money, because down the line they will breed.
But feeding them, housing them - vitamins and doctoring costs a lot of money.
So anyone with couple or more chickens - how much does it cost to have them on the table? And realistically how many eggs do you get?
They are just soo cute!
In my mind I would not have more than a dozen birds.
And I am really thinking about the old ways of keeping chickens, when every house had their dump (basically a compost pile) and the chickens did half of the work with it.
How did it actually work, what went into the trash - what did chickens get out of it (bugs, worms) - did they had to manually turn the dump, or did they just let it rot the used in the spring...
Haven't done any research on it - it is more of a thought experiment.
