Several years ago, I decided that, for a school project, we should hatch some eggs in our living room.
What? You've never hatched eggs in your living room? It's easy. And fun. Really!
Did you know you can borrow an incubator, at no cost, from your County Extension Agent? Ours put us in touch with a local farmer and we got some fertilized chicken eggs. (Again - free)
The Agent also gave us some educational materials about the development of chicken embryos, and we checked some books out of the library, too. It takes 21 days for chicken eggs to hatch, so we learned all about eggs and birds while we waited.
Right on time, the eggs began to hatch, and there was much excitement around here. We kept the chicks for a couple of days (until they began to stink!) and then gave them to a family from church that lives in the country.
