One week later

Chick numbers this week are still asymptoting towards zero. We began the week, we believe, with 4; this then dropped to 3 by Wednesday; and today, Friday, we appear to have only 2 chicks remaining. Ironically, one of the photographs I took several weeks ago appeared in NOCS News this week with a cheerful note about NOCS being the host to two duck families and 18 chicks (which there were when the photograph was taken and passed to our PR department). I must remember to plot this attrition rate up as a graph. Whichever way you cut it, it's not good.
