>>Sometimes I cage them before resubmitting to colony, sometimes I dab
on a blob of honey.  Is there any need to cage them ?

I have not seen the need for it.  I have the frame out with the queen 
on it.  I pluck the queen off, mark her with white out, wait 15 sec. 
for the paint to dry a bit, and place the queen back on the frame.  
The bees immediately orient towards the queen [presumably not liking 
the new smell] but I've never seen bees turn aggressive towards the 
queen because of the marking.
