I purchased what was called Red Rangers, several months ago just to add to my flock. I couldn’t find any definite answers as to what breed of chickens create them except that they are raised as dual purpose birds. These two girls are now five months old and are 6 to 7 pounds. They are so chubby they look like ducks waddling. They are both very good eaters and will try pretty much everything I offer the flock. Even when the rest of the girls turn their nose up at it they will eat it. Can a hen be too fat? They even have a lot of trouble jumping up on the roost at night.
