Hiding for a L O N G time

[Mitch 1.0]

Hi, I fed my corn, and i left him for 1 whold week, then he went into shed, when he shed, that was the last time i seen him out, he went up his branch, and into this hanging canisted i got (basicly a cylinder with one end blocked), and he hasnt been out since, he has been there for at least a week, i dont want to get him out of it as i think it would cause stress, as he is packed in there. I am worried, i want to see my corn. He is 1 year old.
Any ideas on why he is doing it, or wheter i should just pull him out of it, Please help.
