I am curious on how long everyone keeps their processed chickens in an ice bath prior to freezing.
		
		
	 
You are freezing them so you have to consider rigor mortis.  That means you need to age them until the joints move freely after they have gone into rigor mortis.  They do not instantly go into rigor mortis, it takes a while for it to set up, but not a long time.  Mom would cook a chicken immediately after it was butchered, before rigor set up.  That worked.
Most people probably age them before freezing.  You can do that aging many different ways.  Some age them whole, some cut them into serving pieces first.  Some do it dry, some do it wet in refrigerators or ice chests.  Some even hang them, don't even clean them for a few days.  If you hang them it needs to be cold enough to keep insects away.  For all methods it needs to be cold enough than bacteria can't grow.  
I age mine after freezing.  Mine are in the freezer the same day they are butchered.  I keep them in ice water so the heat is gone and pack them thin so they freezer fairly quickly.  If you make a thick package or pile packages together it may take a long time for the middle to freeze.  When I take them out of the freezer I thaw them in the fridge and then age them.  If I plan to cook the meat on Thursday, I take them out on Sunday to thaw and age.  
	
		
	
	
		
		
			I am seeing things all over the board, from a couple of hours to 3 days.
		
		
	 
That's really common on this forum, seeing what you think is conflicting information on about any topic.  The details matter.  In this case if you are going to cook it as soon as you thaw it without aging, then you need to age it before freezing.  If you age it after thawing then you can freeze it immediately.  To me, that is not conflicting information, just parts of two different procedures that both work.
