I have a 2 week buff orp that runs up to the Much bigger 5 week old white rock roosters and does a chest to chest stand off and then flys or runs away. I didnt know if the little pullets acted like the roos or not. The reason i ask is because my 2 buff orp and 2 black assies are suppose to be pullets. They came from Mt healthy and I hope they sexed them right. The other little buff plays the same game but not near as often as the other buff. What do you think?
