Not only are they looking to eliminate the "sow stalls" from their suppliers, but the burger chain has announced that one of their chicken suppliers has started using another system to placate chickens.
O.K. Foods in Arkansas is using a "low-atmospheric pressure system" to knock chickens out before they are handled by plant workers. The system has been considered a more humane way to slaughter chickens (although it has been criticized, it sure beats stunning the chickens with electricity).
Wendy's is also working with their suppliers to phase out gestation stalls over time.
