Canadian feeders does not send them in food cups. Or atleast mine don't come that way but I bring 200/week in at a medium size. They will ship with some food in the egg crate but depending on the batch, most times mine arrive with no food left. You do need to order chow (cooked or uncooked) when ordering worms.
I keep mine on the egg crate in rubber maid tub (deep) As they deficate, tip the crate over the tub to remove their mess. Feed according to how they are eating & growing, but also how fast you want them to grow.
Depending on your house, I find I place a piece of damp paper towel under crate(mist this morning & night but not the worms or crate) to help with humidity for them to shed, otherwise they will not get face caps off and die.
Hope that helps.
