Winchester Cathedral have announced that one peregrine egg has been laid not by the original hen but by a new hen.The original hen ,they think, has actually been killed by the new hen.

Four chicks hatched at Leicester Cathedral, unfortunately the last to hatch didn't survive and was eaten by one of the adults
Looks like there won't be a successful year at Winchester Cathedral. New female Mel (who it is assumed killed the previous long-term resident female Winnie earlier this year, before mating with the resident male William), scattered her eggs earlier in the week; they were placed back in the nest but Mel has now eaten them. Presumably they were non-viable. It is unlikely that she will lay again this season Cathedral's new peregrine eats remaining eggs - BBC News
