Joy's Trick?

I found out today that Joy tried to pull a fast one on a bird.  Our days have been quite windy around here.  And because of that, we have found 2 birds' nests in our yard, along with one beautiful robin's egg.  I was bothered about the loss of life in that egg.  There was nothing I could do.  So, I took the nest, placed the egg inside and slipped it into one of our bushes.  It made me and the girls feel better.  Today, I looked inside the nest and saw this:

Yes, that is a colored Easter egg.  The robin's egg had fallen out and cracked.  Joy replaced it with one of her own thinking that the bird would not notice the difference.  Oh, the innocence!
