Newly Installed Warre - Possible robbing?

[Trawayne]

Help… I may have a problem…
Out of curiosity I walked out to the beehives tonight to see if there was any action at the entrance (after dark, about 9:00 pm). To my surprise, the bees are bearding around the entrance of the hive. I didn’t expect this because its not hot outside tonight (mid 60′s).
Then I noticed there were a lot of dead bees in front of the hive. Looks like it could be a hundred. Could this be robbing? Here are some notes on the hives:
*Both of my hives are being top fed from the inside with 1:1 sugar water.
*The hive with the bearding on the entrance and dead bees in front was started with a package last Tuesday… I guess it would be considered a weak hive. The other hive was started with a 5-frame nuc.
*I picked up a few of the dead bees and a lot of them look like drones.

Is it possible that the nuc-started hive is robbing the package started hive?
Or are the package bees just forcing out the drones to conserve resources?

That is hardly the hint of bearding... serious bearding will cover the whole front of the hive.

That is not a lot of dead bees. You have some bare ground and they are more obvious. Bees are dying constantly of old age.

Thanks for the reply Michael... I am brand new to beekeeping - just got the bees on April 23rd... Just wanted to be sure I didn't need to fix something.

It is always worth watching the entrance to make sure they aren't robbing. Robbers are frantic and there is usually fighting. But from what I can see in the picture my guess is things are fine.

There are always an amount of dead bees in a package. When you dump the bees in, the dead fall in, too. They're probably just cleaning house.
