Robins tend to lay two or three eggs at the most in their nest. Sometimes, while mother is away, another bird lays her eggs in the very same nest. Whether or not the first mother bird frightened away the second mother bird or perhaps it was the other way around... we have a nest of blended baby birds. You can see that the bigger babies have feathers and beaks. The younger ones are pinkish and featherless. Hatched but not "awake" yet.
It is rather a strange sight. I hope the bigger babies don't eat the smaller ones. Have you seen this mixture of eggs before? It is a first for me.
Tucker Update - we will be picking him up Saturday morning!
