That’s so exciting that you have hoglets in your garden. Lucky you!
The hoglets should definitely not be relocated. Sadly, there are hazards for hedgehogs wherever they go and they are best in the place they were born and where they have learnt where everything is, etc. In some ways a dual carriageway is safer than a country lane, because the hogs may be expecting vehicles there and avoid it.

It is mostly about rehabilitated hedgehogs, but explains why they need to remain in their home territory.
You will probably find that some if not all the hoglets will eventually disperse a bit into adjacent areas, so you may not continue seeing them all when they get a bit older. That is normal. They gradually widen the area they visit. It is very different from being relocated, where they wouldn’t know any of the area at all and would be likely to be completely disorientated and very stressed.
Hedgehogs give us much joy but also much worry. That’s the nature of becoming ‘attached’ to wild animals. But they need to be wild and part of that is staying in the area where they belong.
Good luck with all the hogs. Hope you continue to enjoy watching them.
