Is ok to have boxes of raw chicken stacked on top of each other I have a small walk in refrigerator. To save space I stacked eight boxes of raw chicken wings on top of one another on a completely separate shelf from everything else. Is this safe health inspector/ food safety wise?
This should be fine if there is no other food below the chicken wings. What you don't want is for the chicken to be in a position to contaminate other foods.
General food service guide lines include:

From "Preventing Cross-Contamination During Storage Fact Sheet" (appears to originally be from the National Restaurant Educational Foundation, hosted here by New York's National Guard food service):


  Store raw meat, poultry and fish separately from prepared and ready-to-eat food. If these items cannot be stored separately, store them below prepared or ready-to-eat food. Raw meat, poultry and fish should be stored in the following [order (top to bottom)]: whole fish, whole cuts of beef and pork, ground meats and fish, and whole and ground poultry.
