In the dirty thirties there weren't much to eat except potatoes and farm raised chicken. A family of 8 or more would be hard to feed as there was so little food around because of the drought in prairies . Everyone has their chores to do including Sammy, as we see she has collected the eggs from the barn before going to school so that mom can make breakfast for everyone.
Sammy like what she does, she like to listen to the sound the little chicks makes. Her ambition is to be come an horticulture scientist.
