i want to work in East Texas at a place called King Ranch what degree would i have to work at King Ranch?

This is the basics that I have found, which is very general information regarding your question...

Hunting/fishing guides must have their own hunting and fishing licenses and assist those on their trips in acquiring theirs. To become a licensed guide, one should also have certification in first-aid and CPR, as well as proof of hunter education to obtain a hunting guide license.

I will try to look up more information but if you can start working on obtaining the basics, then applying for volunteer work at King Ranch could be your way in the door. Obtain the minimum required and keep putting in your application. If they see you trying to obtain employment and see the eagerness to work for them, someone will take notice, I am sure of it.
