chickens and wild mushrooms... a concern?

[sixchickadees]

I'm wondering if anyone knows whether chickens know which mushrooms are poisonous and which aren't. I know that we have mushrooms in our yard, and ones that could potentially pop up in their run. Will they eat mushrooms, and if they are poisonous, will this hurt them? Or do they instinctively know not to eat them?
Thanks!

My chicks were trying to eat mushrooms yesterday.

. I was sneaking up on them to catch them and get the mushrooms out of their beaks! Sneaky chicks!

I honestly don't know if it will hurt them.
