More Silkie chicks

Another box has started peeping - the peeping in that end of the greenhouse is my first clue there's been a hatching.  Mother hen is maintaining eye contact from the background. This summer, except for the only chick,  the hens have all hatched 5 or 6 chicks from 7 or 8 eggs, and if there's an odd number, it's to the advantage of white.  The white hen (only one, of two, has gone broody), is a terrible setter (three times failed) while the brown hens are all models of success, although none of them have ever done it before.  All the brown hens are last summer's chicks - baby pictures.  But the whites seem to get their eggs in the right place, like cuckoos.This is the strenuous objection pose.  They press their wings down into the floor as a barrier so hard their body tips up until they practically do a headstand.
