Over the last couple of years I have noticed swifts entering my loft via a small gap in the brickwork.The other day though I found 2 white eggs with chicks inside and wondered what happened to them?

- I have also noticed starlings going into the same hole, could it be these that threw the eggs out?
Also how likely ,do you think ,is it that they will successfully breed this year with this happening as I believe that swifts only have a clutch of 2-3 eggs?
Any help appreciated.
