I don't normally worry about these things, but a friend has insisted I'm poisoning myself, so I'll ask you guys what you think!---- Since I'm raising babies in Vermont in the middle of winter, I'm using medicated chick starter rather than plain. Obviously, some of it falls into the litter and then gets taken out to be composted when I clean. To be honest, I know nothing about what the medication's residual effects might be, if any. I've never been particularly careful about what goes into my pile - if it's biodegradable, in it goes! I know opinions vary; some people won't use products from any critters that have been medicated. What do you all think?
