Based on the text that I have read, we should get CAREFRESH to line the brooder with to avoid splayed legs, and to make sure that there is no build-up of bacteria in the brooder. PetSMART says that CAREFRESH is "the ideal pet bedding and litter for parakeets, finches, cockatiels, conures, parrots, macaws and all other birds." Apart from providing superior odor control, CAREFRESH is highly absorbent, natural and biodegradable. It comes in many variants, all of which are non-toxic and pet-safe. It contains no contaminants, added inks, dyes, or chemicals. Made of natural, biodegradable wood pulp fiber, CAREFRESH is sanitized to kill bacteria, mold and fungus. Its natural, biodegradable fiber allows for safe and easy disposal. Heck, some even say that it's flushable (but I'd rather not disprove this theory firsthand).
I'm thinking of hitting the pet shop this week and buying a pack. Price ranges from $3 to $25, depending on the size and the store. I'm particularly interested in the white variant.
