no cedar, oil can be toxic
cherry and walnut shavings are dusty and may cause respiratory problems.
red oak shavings may stain feathers- but no harmful side effects that i know of.
straw allows places for mites and lice to hide, if they arent a problem it is fine.
well I will be keeping them inside until they are feathered. pine is ok then? They wont get a spring time here due to the cold winter season approaching but I will have them a shelter built.
