Nice images of the chicks, very cute.
The bokeh from this lens is interesting, too. They seem to have concentric rings, that look like an Airy disk.

Yes - the source of these diffraction patterns are drops of (out of focus) dew reflecting the Sun and they act like point sources of light. In some of these photos I have seen quite colourful examples.
Here is a full res 1600x1200 crop from the centre of one of the frames in the series.
You get the same effect with a telescope when you slightly defocus it, particularly on bright stars.
