You can still do DL on that kind of floor if you do it properly. I did it on an old oak floor and it did just fine. You may have to clean out the composted litter once a year or maybe even every other year with that kind of floor, but it can be done successfully.
I have a 40+ year old cedar floor.
I keep about 12 inches of pine shavings on the floor and fluff perhaps once per week.
A dozen birds, ~64 square feet.
I'll change out the shavings about every 18 months.
My coop is very well ventilated.
A lot of dust, but no odors or issues.
When I do clean out the shavings, I dump it in their outside run.
With moisture (rain), it decomposes into black gardeners gold within 4 months.
