Scaling a Docker Container While Consuming the messages from Kafka

I have a Docker Container which consumes the messages from kafka broker. In that Container Code, I am creating a consumer group to consume the messages from multiple topics. I haven't tried scaling the docker container, But I want to know what happens if i scale the docker container, Will it consume the messages with the same consumer group?

If they all have the same consumer group then the messages will be load balanced between the containers. https://kafka.apache.org/documentation/#intro_consumers
