yellow/orange droppings

Got our 6 point of lays a week ago, and although not doing it all the time, one of them is passing yellowy orange sloppy droppings.  She is doing the usual scratting around, eating, drinking, and joining in with the other 5, and is quite perky.....do i need to be worried...am putting apple cider vinegar in water, and feeding them on layer pellets, mixed corn and bits of greens....also a few mealworms, which they love...

Thankyou, as a newby i was getting quite worried....

We had a lot of this for a a few days after getting our ladies (again point-of-lay) and I thought it was overindulgence!
We overdid the greens a bit!
