There is no hard and fast description of what a production red is. It might be a cross between a Rhode Island Red and a New Hampshire. It might be based on the commercial egg laying hybrids, probably with some Rhode Island Red blood mixed in. It might be something else entirely. It’s just a marketing name that doesn’t mean much more than they will be some version of red and will probably lay really well. There is no poultry police going from hatchery to hatchery issuing fines and prison terms if someone uses the marketing term “production reds” inappropriately. There’s not even an agreed on definition.
Rhode Island Reds (RIR) were developed a long time ago as a dual purpose bird but with emphasis on egg laying. There were no aggression issues associated with them then. If a rooster or a hen showed too much aggression, they were eaten. Problem solved, then and in future generations.
With chickens unless you continuously reinforce a certain trait in the chickens you choose to allow to breed, the chickens lose that trait. For example, by removing the aggressive chickens before they were allowed to breed, excessive aggression was pretty much bred out of the flock.
Hatcheries and most breeders are no longer keeping RIR’s in a small flock in somebodies back yard or on a small farm where they interact with the family. Aggression is no longer a trait considered when choosing which chickens to breed. Since it is not a criteria, it is certainly more possible that you can get aggressive chickens in any breed, not just RIR’s. It’s also possible you will get some that are not aggressive. It’s just luck more than anything.
Before I get some people mad at me, there are some breeders of RIR’s and other breeds where behavior is a criteria. They don’t have aggressive chickens. It’s not a breed trait as much as it is a flock trait.
With all that said, how much space do they have? Picking like that is often associated with them being too crowded. You can look in my signature down below and follow the link to get my opinions on space.
What are you feeding them? It’s possible they are suffering from a protein deficiency. Feathers are mostly protein. If you are feeding them a feed with 15% to 16% protein (look at the tag on the feed bag for analysis), more is OK, that’s probably not the cause but some people have reported success by providing a higher protein snack, like a little cat food.
Another possibility is just boredom. That can be related to space, but maybe provide them something to do, like hang a cabbage for them to peck at or give them some scratch to dig for. But I’d consider space before anything else.
