i read the messages about deep bedding and it sounds much better than the straw we started using. the flooring under my poles is made of slats 1" apart open to the ground. it's very messy and i hate seeing to much droppings. i may try the idea of a formica-type base and then add the wood shavings. any advice about the light to keep them laying over the shorter days? went to tractor supply and they gave me a brood lamp -my chickens are all adults now and so i'm not sure i want that much heat in their coop. would a grow bulb (like for plants) on a timer help get them to keep laying?
