Our hen was treated successfully, but it wasn't for a sickness, in this case it was an injury: She somehow got one of her talons very loose and it ripped off, naturally becoming infected. The treatment was antibiotics and later full amputation of the toe in question + chicken house rest. She's still living happily, but would've died without treatment. Overall, it was a surprisingly cheap treatment ($130CAD?)
