Opened the coop today and all is well. Seemed fine except for an excessive appetite so can only assume that whatever it was has passed. Thanks for the advice
One of our hens has suddenly become very lethargic and can't walk very well (she can't extend her toes properly). A white mushroom cap was found nearby without a stalk and we assume that the chicken has eaten a poisonous mushroom. Is there any way to create a purge or do we have to wait and see?
