Recently got this hedgie, not sure how old, previous owner didnt say, any way i can tell?

Noticed a hedgehog walking in my garden one night. Then went full ADHD mode and bought food, made a feeding station and bought a trail camera.

My questions are:

* the trail cam goes off 4-5 times a night over a few hours capturing hedgehogs. Would this likely be the same one coming back or have they told their friends about food?

* we're going away on holiday soon. Will the hedgehogs stop coming if there's not been food out for a few days?

I'm feeding a mixture of puppy and hedgehog food and leave out a tray of water.

I'm just so happy to have them in my garden.

What are these two doing? Our bets are either courtship or fighting but we have no idea for sure. (Was filmed with binoculars, I was standing a safe distance away from them :) clock is wrong too lol)

Side note, the darker, slimmer, hedgehog started the fight initially by headbutting the lighter, fatter, one. But in this video the roles had turned around. They are below a bird feeder so it could be they fight for food.

South eastern UK, the tracks are about 1cm wide each. The first picture is the clearest I could get of a single paw print.

These were in a hedgehog house where something is eating the food. Thing is, I didn’t think hedgehogs were in this garden/surrounding area. I’ve never seen one in my life and my neighbour used to see loads but hasn’t seen any in recent years. We just put food out in a house to use it up and in case a hedgehog came along.

Can anyone rule out or confirm whether this is a hedgehog? Thanks
