I don’t know what it us.
But chickens won’t eat it if it’s poisonous and there is enough chicken food available. If they like it or scratch a lot it’s probably gone in a few weeks.

It looks like it could be

I don’t see it on any of the toxic to chickens websites but I would do your own research also more pics will help a lot.

Great that you probably found the plant.

But why the cautiousness? I have plants in the run that are poisonous: Portuguese laurel and Ivy (not the very poisonous ivy). My chickens don’t eat from these plants. Also have nettle in the run they leave untouched.
