One of my split black/lav orpington hens has become a continual soft egg layer. It started here and there last fall and so far this year is seems to be every egg she lays. She is not old, she is a summer/fall of 09 hen. She has full access to oyster shell and grit, is fed purina layena along with the occasional goodie from the the garden or house, she has never been broody either. The group is wormed regularly twice a year and no one has any sicknesses and she does not have lice/mites (I already checked). Her comb and wattles are still normal red as well. The other hens are fine and lay regular and normal eggs. I am totally stumped. The past couple of days I have noticed that she is looking thinner like she is not eating well, she is also acting a bit lethargic but does drink good. This morning DH went out to do chores and found a soft shell egg that had been mauled (have a BCM hen in the pen that will tear them apart) so I am assuming she layed an egg some time in the night/early morning yet again, soft. Any advise would be great.
