Hi hogspot1
Yes, I would definitely put food and water out again, because it is unlikely there is much food to be found ‘in the wild’ at this time of year. Make sure it is good quality food and especially not mealworms.
Are you sure it is the same hog that was visiting before? Hoglets of various sizes often turn up at this time of year – after all the adults have disappeared, so it is a good idea to keep putting food out after you think all the hogs have hibernated.
Personally, I wouldn’t be too worried about 7a.m as it is really only barely light here and I have just been watching a hog on the cam carrying leaves into a nest until just after 7. If you see them around later than that it might be more of a worry and if it was very small.
The hoglets need to reach 450g to survive hibernation, so if it looks very small it might be worth weighing it. If you are going to weigh it, it is useful to have a high sided box, or pet carrier, ready to put it in, if it is underweight, with newspaper torn into strips (or something similar) for it to hide in. Remember to provide food and water if it needs to stay overnight. You should be able to get the number of someone local who might over-winter it, if necessary, or for advice about whether it needs ‘rescuing’ (in relation to your local weather conditions, etc.), from the BHPS 01584 890801.
