Just when there was nothing going on in my life another egg appeared in our abandoned nest. One lonely little egg. Sam noticed this afternoon that there was a Robin sitting in the nest. I took a peek when no one was looking. I had seen a bird earlier this week that looked like it was repairing the nest. I had left it there just in case since I read that a bird might have two or three nestings in a season. Do birds care if they are an only chick?
