First off I find it kinda funny that earlier you had the issue of them NOT eating and now one is OVER eating. HEY at least the xhange has helped one.
I think that candys suggestion is great - by putting just fruit/veggies out first until they are both awake would be such a great idea
Has their schedule been changed recently? I know you said you are just now getting back to things like how they were before you moved.
I know that when changes happen my girls sleeping pattern changes a little as well. Usually after a week though of me being on a strict "this is the time you get fed (8pm)" they get used to it and the second I put their food in and say "it's dinner!" "Goodnight" and then cover their cage they are both flying outta their pouch to get their grub.
They ultimately picked the time they eat cause I would wait till I noticed them sturring around to make their food and now its become such a habit that every night 8pm on the dot they are both awake and ready for food.
My new ones I noticed seemed to have an odd feeding schedule at their previous home. They would wake up at really weird times and be starving. I would put some food in when I noticed them awake (also paying attention to the lighting cause they lived in a basement and now they have the option to get a bright room (shades opened or closed)). I also would open the shades to let even more light in so they knew it was sleeping time and then I stopped feeding during the day and stuck to the 8pm and now they wake up when I feed them.
Maybe try making it a big thing that it's dinner time, mine give me the impression that they don't want to wake up until they know I put their food in.
