Yeah @NatJ I'm not aware of any reasons to avoid them eating bean leaves. I have seen recommendations to avoid them eating the dried beans themselves. The dried beans contain a substance that can harm them. One bite won't kill them, it's a matter of dosage. And if the beans are fully cooked they are OK. Kidney beans are supposedly the worst.
I avoid feeding them quantities of dried uncooked beans. If a chicken picks up a stray dried bean when foraging in my garden after gardening season is over I don't worry about it. I should have harvested the vast majority of them anyway.
