Did you say several hundred dead bees 'in the drawer'? If you did, I'd sure like to see that!
Assuming 'in the drawer' was not correct, it is difficult for me to determine what is wrong based on your description. I've never seen 10, let alone several hundred dead bees near the pollen trap. And I have never seen any bees stuck between the screens.
If there were dead bees in the drawer, please contact us as I will pay to get the trap back to examine it. Otherwise, I suggest you leave the hive for now with the trap off and only the top entrance open. Try putting the trap on again around April 20, and please report back. To contact us, send me a PM or call during working hours at 518-370-4989.
