What have I missed?

[Cherylseptember]

Maybe my mind is on Christmas break already, but I don’t see where I missed anything in the clues.

[Cherylseptember]

Is it possible to complete this puzzle with the given clues?

[dogbertai]

You are correct. Clue #5 is redundant to Clue #10. It was probably meant to cancel out 1 feeder with one of the types (ball or basket).

[Cherylseptember]

So it is NOT possible to solve with the given clues?

[uigrad]

It definitely appears unsolvable to me.

There are exactly two solutions that fit all the clues. The person making the puzzle needs to give an additional clue if they want to make this puzzle solvable.

Agreed, there's not enough info for the ball or basket feeder to be able to solve this puzzle.
