Robin Eggs

One day I noticed a robin going in and out of a shrub.
When the robin left the shrub I went to inspect.
I discovered four blue eggs in the nest. I didn't touch the nest.
Each day I'd peer into the nest when the robin left.
One day I looked in and saw the eggs were cracked.
The next day the baby robins were there but no egg shells.
I looked down and on the ground was part of one of the shells.
The baby robins were featherless and their eyes were closed.
I could see worms in the stomachs of the baby robins;
that's how thin their skin was.
As the days went by the robins started growing feathers.
After about two weeks all the baby robins were gone.
The memory of the robins has stayed with me for decades.
