We kept a few orphans in my youth until they got big enough to start getting mean.
Funny as heck to watch them go at an egg
A friend told me about the hilarity of giving them sugar cubes... as they instinctively wash all their food if there is water there.
They grab the sugar cube with their little hands and try to wash it and it dissolves and they can’t figure out what is going on and just keep taking sugar cubes and washing them.
