1025h - found the kids - they are fine. They are all together again on the roof of the Alt Hotel. Two are on the north side and the third is lying down on the eastside. They have managed to stay up at the 20 storey mark for the last 24-72 hours which is great - and they are all back together. Alt Hotel has a nice roof for them, I can see why they like it (good for fledging, not so for nesting). Wide wall around the edge and metal which can make it warm to sleep on. Buildings around are lower or about the same height and north and south there are clear flight routes for long distances and they can circle around and gain altitude. And they can see the nestsite and the Hydro Building which is where the adults like to sit.
