Increasing numbers of dead brood at the entrance of our hive.

These are not adult bees and most are not fully formed. I just did an inspection and I saw eggs, larvae, and our queen.

We have a 10 frame deep brood box and a 7 frame deep super. The brood box is pretty much full of honey, pollen, and brood. I would say the super is 40% full.

I’ve read mixed things on the larvae and young bees being carried out…some say it’s a normal for space and others say it’s because my bees are very hygienic and can sense varroa/infested larvae.

Has anyone seen/dealt with this?
