Thanks so much! I didn't know that about the straw but it makes sense. Hmm, I have bought shavings from IFA for my brooder box and noticed that there seemed to be more dust all over when I used it. I will have to go get some from CAL ranch. Thanks for the heads up.
Just make sure you get the big one--usually outside in front at our store....the smaller ones by the rabbits are not as nice
