Hi Lola2019,
would definitely recommend you support feed and also provide drinking water. this hog could have awoken as a result of disturbed hibernation site or perhaps too hungry to try and hibernate fully. Its not ideal for him to be topping up entirely on bird food left overs
I would also probably be interested in a closer look at that lame leg if you are able to catch him and maybe get him seen to by a local carer / expert (call them in advance and see what they say also). gives you chance to check how healthy he is generally as well, weight and tick burden etc. Could be a life saver for him. If he’s doing ok then they don’t need to be overwintered if only checked over in this way, and would be fine to re-release where found, even at this time of the year.
