Eggs - Hargreaves class

Dear Hargreaves (and Butterworth and Potter),

After you had all left school on Friday afternoon, Mrs Matthews had a special delivery. As you can see it was two eggs! I was told to keep them safe and under no circumstances to touch them. We need to look at them each day, make sure they are safe and that no one has moved them and then, apparently, something may hatch. I wonder what it will be? Do you have any ideas?
