You are describing typical wax moth activity in a weak hive.
They will move in and destroy a weak hive.
Sometimes they can get so bad, the bees will move out,
If the bees should join in with your stronger colony
result in you stronger hive getting stronger, if you have lost a queen in the weaker hives that is what the bees will do if they have no egg or larva to work with.
The High Temps and no rain in Texas have stopped most all honey
flows and that too will hurt a weak hive. Thankfully the cotton is blooming and some of the irrigation will give a honey flow now.
If you have any useable combs left in the empty hives, you should store them with paradiclorobenzene that will kill any moths present
you can also freeze them
