Is treated lumber ok and mixed wood shavings?

[PersimmonPatch]

Is it ok to use treated lumber inside the coop (probably seems a silly question but a treated pen made my rabbit sick)?
And any ideas if mixed wood shavings from a local college's wood shop are ok? Probably a mixed bag of wood only.

Thanks!

Treated lumber should be no problem for chickens. I've use it for years with mine & no problems. Don't use treated shavings or sawdust from treated lumber.

Mixed shavings are fine - just watch out for cedar & treated shavings. They say the cedar shavings can kill chicks - & if they eat treated sawdust they will be poisoned - old treated lumber was teated with arsnick - now they use copper.
