What not to feed chickens

[lmland]

I haven't had chickens since I was young. I know my mom use to feed them scraps. Is there anything they can not eat? I did see where they should not eat tomatoe leaves. Also the place where I got them said I should keep them on the same diet they were feeding them. Is that true?
