I'm not sure why hides would make a negative impact on feeding.. It's usually the other way around. I have a couple that ate sporadic feeders unless they have a hide. Then I dangle the food in front of the opening of the hide and they take it so fast it scares me every time. Snakes prefer to be ambush predators. It's more natural. I bet removing the hide is what is snapping your snakes out of feeding mode. You've just startled them, disturbed them, and the last thing on their minds at that point is food.
Kind of like why many more snakes who are fed in a separate enclosure are sporadic feeders. Simply touching them or changing anything about their environment can snap them out of wanting food.
