all my chicks started dying after i switched to this bedding. I cannot believe I did such a stupid thing w/o first doing researching on this new product.
So to be clear this bedding was sold by
TSC but is a product that can be bought elsewhere. Please consider editing your title to "coffee ground bedding"..., Looking at the manufacturers website it's also sold at Rural King. Interestingly enough, the contact us page on their website comes back blank!

Just yesterday I saw someone suggest that if there was a picture of ducks on the feed then it must be good for ducks. I told them never trust pictures and I clearly see a picture of a chicken on this bag. However, the safety stated on this bag indicates, even reading the directions doesn't protect you,

As a non food product, I doubt ANY testing was done or required to make such a claim.
I am sorry for your loss,
and thankful for your commitment to see this through with necropsies and samples!
@humblehillsfarm I saw a thread with you using starbucks.. have you used this bedding for chicks?
