I'm not too picky about what size pieces my chickens try to eat. Never had a chicken die of it, either.
I have given lots of table scraps, weeds, bugs, etc to hundreds of chickens of various ages over the past several decades.
There was only been one time I had to remove something from a chicken's mouth: a t-shaped piece of tough meat gristle leftover from dinner. The leg of the "T" was partway down the throat, the crosspart was across the beak so it couldn't go down. The chicken just kept trying to swallow it, and did not appreciate the help. But she was clearly making no progress on swallowing, so after a while we caught her and pulled it out.
Other than that one time, my chickens have always solved things for themselves--they put it down and try again, or another chicken rips a piece off and it gets smaller, or they swallow it down somehow.
