I have five red sex linked hens that are one year and ten months. They started laying Sept 20 2010. Layed pretty much an egg a day once they got out the initial kinks. Layed all through the first winter. I gradually switched feed from Purina Layena to Countryside Organics starting Dec 20 2011. Since switching feed I have noticed smaller droppings. Didnt seem to eat as much as they did with the Purina. They like it when I moisten it with water. Try to provide both dry and moistened. They are fed free choice with greens and a little apple late afternoon. They always have grit and oyster shell and I give them their egg shells. I have always had some shelless eggs but there has been a dramatic increase. Big decrease in production in general. Could this be due to the food or possibly their age? Do these hybrids take breaks like the purebred birds? I would hate to think it is the food. I thought I was doing them a favor.
