Injured foot

[nightnurse]

So looked in the cage this afternoon and saw blood all over Darwin's marble slab. It took me a bit to find the injury- hind left foot. I can't tell if it's cracked or maybe a tear from a splinter of wood. I've put on blu-kote. Cage is washed down and I've sort of restricted his cage. The bottom half of the ferret nation that contains his wheels and higher shelves is blocked off. He doesn't seem to be limping and I thought he was acting a little off but he now appears fine and is eating hay.
My question is how much should I restrict his jumping? Should I take out his 2nd smaller shelf and accessories? I will be watching very carefully overnight and the slightest sign of infection will be a vet visit. I'm going to call and discuss with them right now as I am aware of how quickly these things can get worse. Input appreciated. Thank you.
Not sure why the last pic is upside down- I suspect new glitch with windows 10 automatically turning photos off my phone.

if he is not acting like it hurts, I would give him full access to everything in his cage. As far as I can tell by the pictures, it looks like he has some dry skin in his feet. Rub a little vitamin e oil into them and he should be fine.
