Cheers Wood. Will they unblock it themselves when they want to forage or should I keep doing it?
They will more than likely unblock it themselves when they need to come out to forage. It may be that they have a good store of seeds inside the nest, in which case they may not need to leave for weeks or even months; but if you get concerned about it then unblock the soil, although they might still reseal the nest entrance, and ants can live for a long time on very little food when they enter a more dormant stage such as semi or full hibernation.
I've not seen any above ground activity since watching the access getting blocked up. There is obviously some still going on as it's been unblocked since. I've caught glimpses of movement in the nest area below ground but that's about it. I put some turkey in the foraging area but they didn't take it.
