How many rounds did the squirrels 🐿️ came?

Today I tried this. I made a hazelnut train. 😂😂😂 There were 50 hazelnuts. I left it there at 11:00am

And here is the result at 15:10pm. There were 13 hazelnuts left. So this means that the squirrels have to do 37 rounds. 😱 

In four hours it toook 37 hazelnuts. The squirrels were hard at work. 

Updated @18:10pm - The hazelnut train was wrecked! 😂😂😂 Only 4 left. 

Little Missy came this morning
