I have a batch of 12-day old chicks that I've had on paper towels since day one and 5 days ago I put aspen shavings on the floor and covered them with more paper towels, planning to take them off 5 days later (today). Well, I took the paper towels off today so it's just the shavings and I'm worried because the chicks seem to be eating the shavings (or at least pecking at them an awful lot) and scratching themselves as if they're very itchy all over. About half of them are at least partially covered in shavings, either from "dust bathing" in them or from them being kicked up on them from the other chicks; they're also kicking them up into their food and water. So is this normal/anything to worry about?? I'm concerned it might harm them in some way. The shavings are LM Animal Farms Aspen Bedding (link) if that makes any difference. Has anyone else here had experience using this stuff? Or know if this sort of thing is normal/okay? Thanks for the help.
