Hampster bedding ok for chickens?

[ChinoChix]

I have got to get rid of the wood pellets I have been using, they are SO dusty and making my allergies worse. I only have 6 hens.
I bought some Care Fresh Natural paper bedding that's used in hamster/ferret cages and tried a little in their nest box before putting it all over their floor (they live in a tack shed) and my Polish hen started EATING it, so now I'm afraid to use it.
Do you think she will eventually STOP eating it or will it harm her if she does? I'm getting some new chicks this week so I'm thinking about using it in their brooder.
Is hay just as dusty as the wood pellets? I have not tried hay on the floor, only in their boxes.

I had extra hampster fluff too, and my girls tried to eat it too! But they did not stop after a few minutes, so I cleaned it all out and put in pine shavings. I think pine shavings have less dust than straw.
