What kind of container do you use to put crickets in to feed the bluebirds?

To keep crickets alive, put them in some kind of aquarium or tank. But it MUST have a screen lid so the insects will be able to breathe. Put some potato halves inside with them as it works as food, and it hydrates them. Replace it when it becomes too dry. Also, they like having some egg carton pieces in with them. Hope it helps!
