Now at 5 eggs... 2 pairs, plus a first egg in a third nest. Guess these birds have their cycles in sync.
Great romantic that I am, I always put my pairs together on Valentines day. By the end of Feb. almost all pairs had eggs. I would take the first egg, replace it with a wooden egg, store it in a shot glass on the bedroom dresser, and then return it when the second egg was laid two days later. Prior to doing that a lot of first eggs got chilled and were not viable. It's that time of year for 'flock explosion'.
