Whose Who.

The Robins have three young ones in the nest. Back and forth all day long with grub for the family. Love to know which is the male and which is the mummy. Am told the only sure way is DNA sample.  So, for now, main photo is robin A. In extras it is robin B. C is where the nest is above the Xmas wreath by back window. No nearer to finding out which is which, but they are both there !
