A year ago we got RIRs and they had a white lacing just on their belly, they were just a cross of RIR or production reds.I don't even think the stores know the difference.
We also had a RIR Roo thatw as supposed to be a pullet. I had a thing for my little sister (who's 5) he would chase and chase her across the yard. Not anything else just her. Well he's been dead for about a year now.
One of the problems with RIRs is that they can be aggressive with the chickens. I have 6 RIR chicks and just got 6 other breeds of chicks and they are doing reallly well even though they are 4 days older than them.
Yes!! We had a RIR 3 years ago that was really mean....bute we have 9 now that are so sweet. It just depends on how they were treated as chicks I guess.
