Hi Bearfoot,
I looked at the site you listed. Read the whole page. I must be missing something because there is not one single thing listed on the pesticide site that shows cedar is harmful to humans, chickens, or any other animals.
In fact, if you open this link
http://www.epa.gov/oppsrrd1/REDs/factsheets/3150fact.pdf you will see this comment "natural cedar products which consist totally of cedar wood, are not combined or impregnated with other substances, and are intended only to repel arthropods other than ticks and/or to retard mildew. EPA believes it is unnecessary to regulate these products because they pose little or no risk to human health or the environment. Consumers are not likely to be exposed to significant amounts of cedarwood dust or oil, either dermally or by inhalation, when using these products. EPA is not aware of any evidence of injury to human health or the environment due to their use."
The "Kind Planet" link is simply a list of publications written by a whole bunch of people but there is no way to tell what those publications even say. Moreover, if one goes to
www.kindplanet.org they will get a better idea of what the organization is about.
Here is just a small portion of their home page: "Holism is the foundation of our approach to Humane Education. Kindness and compassion will become the foundation of mankind's consciousness and will govern choices. As we evolve towards that state of awareness, we will find that all life must be honored."
I don't know about y'all but that's not exactly an organizational mission statement that would lend me to putting a whole lot of stock into anything they have to say! I didn't spend a whole lot of time on their website but from what I can see, they are just another one of those folks that think animals have all the same rights as we do.
So, with all due respect Bearfoot, neither of the sources that you listed persuade me at all that cedar shavings are harmful to birds. In fact, the EPA statement on the one site would lead me to believe just the opposite.
Taken in its natural state, used appropriately with plenty of ventilation, and I would say used in the proper amount, I still think cedar shavings are safe. Like I said before, I haven't lost a single chick or bird yet and I use them.
God Bless,
