Ok so I have a white Japanese bantam hen(lays white eggs) two silkie hens(i just got them) and a white leghorn hen(which I have had for 2 years and is yet to lay an egg)! And I just wen out to check on them and the leghorn was in one of the nest boxes, and she ran out when I walked in! And there was a light brown egg in there!! And I have seen one of my silkies in there today as well!! Which chicken layer this egg? My silkie hen or my leghorn hen? And it was also kindof small which makes me thin it was from my silkies!! ( it was the same size as my Japanese bantams eggs!!
