White Ceramic Rooster/Chicken Teapot w/Green Checkered Bottom

Charming vintage ceramic teapot featuring a colorful rooster design. Includes a lid with a rooster handle. medium sized, approximately 9 inches overall. There is a small on the inside of the teapot. I checked it is not all the way through to the outside. Please see pictures. there is no signature on working on the bottom of this pitcher. Did some investigating most places say that they believe it is from Fritz and Floyd?
