This particular ledge is near St Philip's Stone on the west coast. Today, I know that there are at least 3 chicks, and I'm expecting more to hatch any day. It looks like there could be 13 chicks when they've all hatched.
Things seem to be slightly behind this year. On this day last year there were 11 chicks on this ledge and they received a total of 15 feeds from their parents in 2 hours. This is an exceptionally high rate - usually a chick will receive one fish in 4 hours.
