I sincerely hope that today was not a fluke, but we have gone from getting one solitary egg a day for just over a week to getting four today - I thought I had hit the jackpot - I came screaming into the house, shouting, "The vinegar's worked - look!!" and I am sure the FH thought I had flipped (again!) but hey, something's happened in the hen house, and I am pleased as punch. Now, 4 eggs from 25 chickens is not great, but it is a huge improvement on one!!
