how did entering the shead go? did you leave the door open?
It sounds like it has made that places its home for now ...I should of read post more clearly but just wanted to let ya know it probly wont bite you.
long busy few days here sorry mind not focused when over tired.
if your really scared grab a rake and bat it gently towards the door.
or throw blanket over it .
hope things are working out and it leaves on its own.
