I am wondering if I could use my shredded junk mail and shredded newspapers mixed in with the litter for the coop bedding, and later compost it for the vegetable garden? I have removed all staples and plastic windows from the mail. I know that newspapers are supposed to use soy based ink for their papers, which is non toxic, but don't know if junk mail falls into the same category. I don't want my chickens to eat paper with toxic ink and I don't want to put compost in the garden if it contains toxins. I am just trying to reduce the amount of stuff we throw away or recycle, but don't want to cause any damage to my birds or the garden in the process. Any help appreciated.
