What percent of humidity is too much in a coop?

Anyone know at what percent of humidity too high in a coop? I have a quite a lot of ventilation above their roosts but where they are my hydrometer says 50%

I read on here earlier today that 50-70% is good. Higher then that will start issues.

Thank you! I was concerned that my 50% was too high.

If you have adequate ventilation humidity inside the coop should be very near the same as outside the coop.

I don't even measure anymore.
