He is that small. His brother and sisters are just as small as him. His dad is a class B Serama so he isn't very big and his mom is as big as the dad just a little butcher. So RooPaul wont be very big.
I randomly googled "RooPaul" and found this post on BYC. I also have a chicken named RooPaul........ I love the name! I named him it because he looks like a hen!
Those little serama roosters are sure determined We have one that tries to mate with our NH and other larger hens too......mostly ends up just riding on their backs and looking confused
