Hi
The hog sounds poorly. Well done for rescuing it, but you need to get it proper help
Green mucus poo could be a sign of internal parasites that have got out of hand and/or an infection
Being alert is not necessarily a good thing – it can also be a sign the hog is in pain
Their internal clocks are pretty good and it shouldn’t really be up and about in the daytime
You’ve not mentioned if it’s eating and drinking properly?
Is it sleeping on the hot water bottle? If so again not something a healthy hog would want to do
I stongly suggest that you contact a proper hedgehog carer and take the hog to them. ( They will happily let you have it back once it’s fixed )
Hedgehogs in captivity can suffer a lot of stress which can make it’s problems a lot worse very quickly
I will also say that an ill hog only let’s you have a short window in which to treat them so getting help quickly is really paramount
