Nancy Talbot, from the research team BLT, was kind enough to write me back when I sent her this photo.
Nancy says to date no researchers have arrived at the scene of a bird's nest that's been undisturbed. She says frequently the first ones to find the crop circle are the same ones who find the eggs; often an empty nest is recovered later on, with a broken egg or two, but the serious-minded researchers haven't been lucky enough to get a pristine egg...
She believes the eggs are no longer viable, because of the mircrowave-type disturbance within the circle; however, she was quick to say that is her belief based on the science that's already been done with respects to the shafts of the crop. But it's also interesting to note that the grain does NOT stop growing when it's been affected; it continues to grow -- it just looks mutated, which of course, it IS! So... until someone gets to a crop circle within MINUTES of it's appearance, and has the science of mind to gentley recover the eggs and submit a couple for testing and a couple into an incubator, no one can know with absolute certainty if the chicks would hatch or not, and if they were to hatch, how the molecular structure at the cellular level would test out.
Some days are DIAMONDS; some days are STONES!
