For those of you who use hay...why do you like it?
For those of you who use pine shavings (we use this in their coop already) do you just turn it on a regular basis to keep eggs clean or?
I use pine needles raked from my yard- FREE.  It seems (I am a new chicken owner this year) that when and if they poop on them in the nests...the poop only sticks to a few of the pine needles, and I can just pick them out and toss them, leaving the rest in.  (Do those of you using hay find the same scenario for clean-up?)  
I am just worried about (as I said earlier) ease-of-clean AND more importantly, egg cleanliness.
