I've confirmed that the wildlife ranch permanently closed at some point earlier this year. There is now a farmers market at the sight (called R Lazy J Ranch Market). I do recall that this zoo had some interesting species come and go over the 4 or so years they were open to the public.
US zoo closures in 2024 (so far):
1. SeaQuest Littleton (CO)
2. Sierra Safari Zoo (NV)
3. Texas Reptile Zoo (TX) - as a publicly open facility
4. Grapeland Safari (TX)
5. R Lazy J Ranch (AZ)
