Heritage RIR's are of the Heavy or Large Fowl groupings.. your red probably is a production red, which is two different things. Typically, production reds are smaller, as their use is geared for egg production, not meat. While heritage RIR's are considered a dual use bird. Our RIR rooster at 23...
Finally my trio are looking good. (22 weeks, last Friday) My rooster Meatloaf, is filling in very nicely. I am not sure why, but I am so proud of these three.. In my eyes they are just as beautiful as a RIR Could be. ( I don't show, so... heh, I could be way way off ) But I just love the lines...
The ones you are holding look near exactly like my new chicks. I did, however, search for a breeder that their birds had true heritage RIR traits, like having the dark mahogany -almost black- in colour plumage, as well as a really nice and defined brick body shapes.
Sooo getting very excited about my hatch in 7 days. First time adding heritage RIR to my flock. The parents are deep mahogany, nearly black, and excellent brick shaped. Yays! Can barely control my excitement. :D
