Hi Antique
I would try to get to the little hog checked over by a hog carer/rehabilitator. You can get contact details from BHPS on 01584 890801. It’s not normal for a healthy hog to have flies around it (also a healthy hog wouldn’t lie flat to the ground to hide) and it may have some injury or underlying condition which is not easily visible. They will at least be able to advise you – you will be able to give fuller details to them. The BHPS phones are still answered out of office hours so you should be able to get contact details of a carer.
Good luck
