Double Budups

I went out to the coop in my panda pj's to see if there were any new eggs under Sammy.  When I got there, I saw an extra tush poking out.  

I saw a little Sunset butt sticking out.  I reached under Sammy and pulled out an egg.  I turned it to see if it had the mark I put on it.

It did have the mark.  The mark was "3 days."  I put it in the nest.

  Sunset started tucking it under herself.  It was too big for her so she stuck it under Sammy.  

I wonder if they will raise the chick together?
