Mother and Father are Doing Well

Can I move on to my birds now and forget the test card for a bit. Mr. and Mrs. Swallow (not Swift) are getting very excited, I think we have moved into the maternity unit stage, the eggs are surely going to hatch soon because Mrs. S is on that nest all day long and Mr. S is flouting visiting hours and popping in on a half hourly basis. The problem is I am working right by the nest and have to walk through the light well every time I have to get to the house or the workshop and they get a bit startled by me. Does anyone know the gestation period of the swift; it’s got to be soon now?

Meanwhile in the workshop I am working of the queen of all imaginary birds.
