You might know that there are two fuglekoje on Fanø. They can easily be reached by car, bike or by foot. One is Albue Fuglekoje and the other one is called Sønderho Gamle Fuglekoje. They have been used to catch ducks in the past, however, today they are a kind of open air museum.
But if you do a little research you find that there are more fuglekojes on the island. This small riddle leads you to one of them.
In order to find the cache, you have to answer these questions:
A. How many fuglekojes are there on the island?
B. In which year was the use of fuglekojes banned? You need the cross total.
C. In which year was the first fuglekoje built? You need the cross total.
D. Which fuglekoje had a special form? You need the sum of all letters (A=1, B=2...)
The final coordinates are
N 55° (C+1).(C*B*3-269)
E 008° (B*2-1).(A*D*3-202)
