You are in Texas, so there is likely grass clippings available from your yard, or someone else. I would layer a 4 inch deep ground covering into run. The chicken gumdrops would get mixed into grass clippings and smell would be MINIMAL....
You would in fact be creating a Deep Litter Method, or just enough mulch/grass clipping environment. (some call this Deep Layer

) DLM does not create fiercely unpleasant odors if done correctly.
I have a large run area, and place ALL my grass clippings in there. The ground stays clean looking and the gumdrops get scratched into the grass clippings by the chickens themselves. It also keeps the ground from getting muddy during rain.
Just wanted to add this lil note. Feed that is higher in protein than what the chickens
utilize in their digestion sometimes tends to create runny, possibly more smelly droppings.
WISHING YOU BEST,,,,,,,,,,,,, and
