I use shavings for everything, for multiple reasons..... Like some other people said CHICKENS EAT HAY! And yes, it can lead to an impacted crop, which requires surgery. My chickens like to dig in it and stomp through it and everything else they could possibly do to grind it into the dirt. Also, straw up here cost $9 a bale! UGH! And my neighbor has a mill and gives me shavings for free... YAY! He says that if I didn't take them he would have to pay somebody to haul them away!
So I would suggest that you gets shavings but it is your personal choice...
