I believe I have found a solution to my issue. There are two articles that someone has directed me to:
What is Fill Factor? Index, Fill Factor and Performance, Part 1
What is the Best Value for the Fill Factor? Index, Fill Factor and Performance, Part 2
Both articles give a complete overview of fill factor and possible solutions to what values to use.

In my case, I DBA directed me to use a maintenance tool for SQL Server on Ola Hallengren website. The SQL Server maintenance script will allow me to rebuild and reorganize all my existing indexes. Thanks for everyone help.
