What does Tom Robinson's dad send Atticus? What else is brought to the Finch home?

I think that what you are asking about can be found in
Chapter 22.

In this chapter, the trial of Tom Robinson is
over.  Tom has been convicted of raping Mayella Ewell.  Even so, the black community in
Maycomb is really grateful to Atticus for defending Tom.  So they have sent him
stuff.

Tom Robinson's father has sent a chicken.  Estelle
from the hotel has sent rolls.  A lot of other stuff has been sent as well.  Calpurnia
says that most of the other stuff was left on the back porch and was there when she got
there that morning.

The kitchen table was loaded with enough food to

bury the family: hunks of salt pork, tomatoes, beans, even

scuppernongs. Atticus grinned when he found a jar of pickled pigs'

knuckles.
