Thugs

Now that the chicks can fly they take full advantage of their abilities. This is wonderful! We want them to fly out of the day pen and act like real cranes foraging around in the marshes.

We check on them once an hour, or so, to make sure they are still alive.
The problem is that once they spot the costume, they start following it like a group of thugs looking for an easy victim who will cough up his treasures (i.e. grapes) without too much of a fight.

Look at these guys. Don't they look a little menacing?
