I think poultry refers to ALL sorts of birds, such as Turkey and the like, whereas chicken is only one type of poetry. So they aren't technically different, but poultry is a much broader term.
Answer: Poultry are domesticated birds used for meat, eggs and feathers. Chickens fall into the poultry category. So, no they are not the exact same thing, chickens are just a part of poultry.
