The boys brought the egg to school and showed it to their teacher Sara Valgren, so today class 5a at Svärtingehus has devoted all lessons to finding out the facts about ostriches.
Hear Rasmus and Albin tell us about the ostrich egg they found in the forest in the video above.
The nearest ostrich farm is several miles away, as is Kolmården's zoo. Do you have the solution to the mystery of the ostrich egg in the Black Forest? Please contact me at tobias.holmqvist@svt.se.
