In my limited experience, I am seeing that my chickens will eat what they should, and generally leave alone, that which they shouldn't eat. But, we all know that birds aren't the brightest creatures around, and I do occasionally see them pecking at pieces of plastic, a pen laying around, many things they can't, or shouldn't ingest.
What about mushrooms? Specifically, poisonous ones?i found a huge white mushroom, in the yard, yesterday, in an area where the birds like to roam. It looks like the biggest white mushroom, (like the store bought kind) I've ever seen. But, I think it's a toadstool, poisonous mushroom. I plucked it, so that it's not right on the ground, for the birds to peck, but, I have 15+ acres here. Lots of tall grass, and woods. If there's one, there are more that I'm just not seeing. Should I be concerned? Or, will they just avoid the poisonous ones?
