Someone had suggested I add scratch grain to my layer feed to add extra source of grain. So I noticed that my hens were eating just the grains and not eating their feed. I've taken away the scratch grain to get them to eat their grain again, but they are protesting! Not eating any of it. How long should I hold out? Can they live on scratch grain alone? They are all laying almost daily or at least every other day. Will this halt everything? They have a run and pick bugs and such, but have eaten all greenery. We live in Florida, near the ocean so I assume they are still getting some calcium naturally present in the sand (as we really have no real dirt) and there are a plethora of insects as you can imagine. Should I just give in and give them back their scratch as they seemed to being doing fine on just that? Or should I continue to pursue the layer feed only tactic (if they go hungry long enough will they eventually eat it?)
