Hello and welcome to BYC!
Glad you joined.
Coop cleaning frequency depends on the population density of the birds to the coop size and how long they are confined to the coop and the poop management technique.
For example, I use poop boards in a coop that (currently) provides 4.2 sq ft per bird but has a predator proof attached run that provides another 15.3 sq ft per bird. Before they get let out of the run for the day into their pen. I clean my boards each morning and clean the coop once or twice a year.
