In the early spring, we sent off several of our eggs to a homeschooling family for use in a science project. The kids wanted to compare and record the hatch rate between different chicken breeds. So, they purchased an inexpensive incubator and mothered the eggs diligently for several weeks.
Since chicken keeping is not allowed in their municipality, it wasn’t long before thirteen chicks were sent back to us. Seven of the chicks were our own hens’ progeny; six were purchases from tractor supply after the first batch of eggs failed.
