Mrs GT fetched some more nesting material this morning.
It looks as though there are still 8 eggs in the nest so it seems that laying has now finished. Assuming incubation has started then we should be able to look forward to the first hatching sometime near the 16th May. Better weather should increase the insect population which will be needed for all the food these, and those in other nearby nests, will require.
