[QUOTE 3741078, member: 9609"]Day 16 - we now have three eggs in the nest, I would guess she will lay another one on Friday then start sitting - they don't start incubating the eggs until they are all laid, this ensures they all hatch at the same time and will then get fed equally.
I do worry about
@raleighnut comments that the aluminium will suck the heat out of the eggs, this is not normally a problem we have had many successful nests on these ladders for many years, but this nest is very poorly built, probably the worst Swallows nest I have ever seen, normally there is a lot of mud and straw under the feathers, I am not sure there is anything under the feathers in this nest, and in comparison to previous nests there is not many feathers either.

There is nothing you can do, if you interfere they will simply abandon. Just let nature take it's course.
The feathers may provide enough insulation to keep the eggs warm enough to hatch successfully, hope so anyway.
