Souunds good
I had a ery eventful two days with them, on sunday them came out of the nest, but the queen couldn't get out because of the sand bloking the tube, so she went to the bottom of the tube [where it was flooded] and 'drowned' I managed to get her out and the workers were crawling on top of her trying to help her, I thought she was dead
I wok up in the moring and she was alive, i was very glad. Today they havnt done much, just started to make a nest in the basin.
