Children's PLAYSET Coop idea? ? ? ? ? Could it work? ? ?

[Sirpug]

Hi everyone; long time lurker, first time poster. I'm trying to plan for a coop and run but space is very limited. I saw this thread and it got me to thinking but I need some advice from people in the know.

I'm thinking about using the lower area below my son's fort as my coop however I need to know how sensitive chickens are to noise. While the play set doesn't get a lot use, it does get played on when he has friends over. Will the chickens be effected if they are in there and some 6 year olds climb up and start jumping around?

Thanks
