With backyard chickens eggs, the flavor is way better and they have more nutritional value.The last time I kept chickens I was maybe 10 years old and that was half a century ago.
We go through half dozen eggs a day on average. Most of that is probably our pooch, but I can easily go through 2 - 4 a day, if they're sitting there hard boiled in the fridge.
Is there a rule of thumb of the number of eggs one uses when it becomes cost effective to raise chickens for eggs? It would be so easy to up our consumption if we're close to the break even point.
I think our spread can support a small flock, but I need to weigh the added work against the benefits which would include consuming ticks from the grass.
Once you have seen and tasted the difference, there's no going back.
That makes the cost effectiveness a moot point for me.
