A proper Queen does not let her hive starve.  She will feed each and every changeling in her hive off of her own love for them.  In turn, they will feed her to keep her strong.  A proper hive is self sufficient, it has to be to sate the never ending hunger of the changelings.
In an unbalanced hive, like Chrysalis’s, yes.  The psychic link of the hive mind makes the Queen experience the thoughts and emotions of all of her subjects to a very muted extent. 

Fickle, you know that headcanon is true.

To anyone who hasn’t already, there is a group RP group for those who have joined the hive.  If you want to join, just add me on skype. 

Drones, warriors and workers can sense love within a few yards, and only when they’re actively searching for it.  A Queen, having a much more powerful psychic presence, and much greater hunger, can sense love for several kilometers if they are hungry enough.

Changelings are slightly psychic, and when hungry will sense an aura of love around individuals.  The love they sense doesn’t have to be directed towards them.  It can be general love radiating out of a pony like water from a sprinkler, or directed love being pointed to a single individual.  
A changeling can feed off of general love, but directed is far more filling and nourishing as it’s more whole and, well, direct.  To feed off of that though, a changeling must replace the one the love is being directed towards. 

She might feel a….special tingle, but it’d be faint.

When Papi converts someone they assume a base form of a typical changeling drone, so only one horn.  If the drone maintains that form completely, or changes it to suit their own tastes, then they may.
