Albatross spitting feathers (5)
I believe the answer is:
cross
This clue is a double definition.
'albatross' is the first definition.
(both can metaphorically mean a burden)
'spitting feathers' is the second definition.
(spitting feathers means angry or upset)
(Other definitions for cross that I've seen before include "Get on wrong side of" , "mule, say" , "Angry; intersect" , "Traverse - displeased" , "Grouchy" .)
