First, don't worry about pinkies, or if they eat them or not. I know I don't. You need only to worry if the monitors are progressing. That is, eating and growing.
The first thing to to understand captive husbandry. Cage control is important, not the cage itself. Keeping the cage inside certain areas like, not too hot or too cold or too dry or too wet. To have ventilation but not so much that it causes dehydration. All of these will determine how the monitors do and of course their choice of food.
The monitors you have were indeed feeding on crickets and pinkies. Why they do not for you, is of course your conditions. But before you jump around changing this and that, make sure you give them some time to adjust to their new enviornment.
Without a doubt, shipping can effect monitors, some have no problem so have problems. For instance, I just shipped Ian two monitors, the same exact way I shipped yours, his ate within hours of unpacking. Yet, he lives in a very cold area. You don't. Hmmmmmmmm. You see, we do not have any idea, or control of what happens to the monitors once they leave here and arrive there.
All you an do at this time is to work your monitors back into shape. They will indeed eat pinkies and fuzzies. Your job is to make sure the conditions are within normal ranges for them to pick from.
The type of monitor you have is very strong and durable. You should not have a problem. It really does not matter if you have them in a rubbermaid, aquaria, or other cage, its the conditions within those thats important. F
