egg song after laying egg

I picked up my 8 year old daughter from summer school and told her when we got home that mike was sitting in the box earlier when I checked on the chickens before i left to get her. We get home and theres an egg. she took the egg and came in the house and then went back outside and called me outside and said mom listen whats this noise. we recorded it and stood there listening and laughing mike was singing the egg song.
