This can also be accomplished by setting the CSC_OPTIONS variable properly for 
chicken-install:

CSC_OPTIONS="-I/Users/bsweene/.local/Cellar/openssl/1.0.2f/include 
-L/Users/bsweene/.lo\
cal/Cellar/openssl/1.0.2f/lib" chicken-install openssl

without any modifications.

Does that work?

Kind regards,

Christian
