Are they in season maybe?
For the last couple of mornings, they have stood by their poo pile,  heads facing inwards, all four of them - look like they are in a rugby scrum.  Normally the two bigger ones, run the little ones off, but all seem very agreeable, for a few minutes, then go off their own ways!!

I'm afraid I'm no expert and couldn't possibly advise you - but have to say that it does sound quite comical 

[Roxy]

  Yes, it looked like they were having a gossip - only noticed it the last two days though.Well, they are out of luck as we have no fella here for them

[Berkshire Boy]

I would have thought not, mine get a bit bolshy with each other when in season.
 We men all know about that don't we guys.

I don't I stay out of the way
