I will be taking photos of the locations of hidden items as I find them. I have never made a guide before so this will be a mess.
 
 

Notes

I have reason to believe that you need to find the items in order starting with the bottle.
 
after you find an item you must finish the day for the next one to spawn.
 
 
 

Bottle location

 
the bottle is the first item I have found and can be found under the stairs in cell block B. you can get it day 1.
 
 
 

Soap location

 
this is the second item I have found. it is on the floor next to the dirty towels bin in the showers. you must be at least level 6 to enter the showers.
 
 
 

Pigeon feather location

 
the feather is the third item and is found between the basketball court and the seating area in the yard.
