Is Honey Locust tree poisonous to chickens?

I might be using a branch of a honey locust tree as a perch. Is it poisonous to them? I've heard black locust is.

I didn't realize black locust was poisonous. I just build a fence with all black locust posts

Well, I thought I saw it at a website, eating the bark is supposed to be poisonous.
