Only 3 heron again today. No sign of the older female. The young one flew to meet me then flew back to the edge of the loch. She got most of the fish I had taken for her and the absent older female (I gave some to the crows - there were about 5 of them today). I then went to feed the males, they are definitely improving. After a little laying down of boundaries they actually eat closer together. I do have to make sure the older one is fed then quickly feed the younger one.
