Can a hedgehog fit through chain link fence?

My neighbour has, after 4 years suddenly had a new fence installed. (Which was falling apart... but great for the hedgehogs! The problem is I have a hedgehog hibernating in my garden & I don’t see how it’s going to get out when it wakes up now as the rest of the garden is surrounded by chain link fencing (can’t remove as I rent) 

can a hedgehog fit through this type of fencing & what am I meant to do when the poor thing wakes up ?
