The Mad Fisherman

When I was alive I was never in here, but I did make sure the rich nobleman who lived here went bankrupt, because his profitable fishing company went under.

The next task isn’t about him though.

Here you will find the home of some of my friends: The birds.

They helped lure the fish away.

Every birdhouse has a bird pair, with chicks.

The birdhouses, that hang on beams that are not adjacent to a window, have at least 1 chick.

The birdhouses, that hang on beams that are adjacent to a window, have at least 2 chicks.

The birdhouses that hang over a window have 3 chicks.

How many birds live in all the birdhouses?

Enter the number here: (xx)
