I bought 3 SS pullets but after getting them home started suspecting I had a roo. There was at least one that would charge my hand and peck me anytime I reached in to feed them or give them fresh water. I then realized that one of them was maturing and growing a lot faster than the other 2. I am a newbie and have no idea what I am doing but I figure I either have 2 roos or 1 roo because of how differently they have matured. One of them got all of her feathers more quickly and is just as big as the Barred Plymouth Rocks I got at the same time. She also tends to stay with the Barred Plymouth Rocks. The other 2 are still getting their feather in (they are almost done but have been about 2 weeks behind) and are a lot smaller than the rest. They tend to steer clear of me and are always together. I would be ok with 1 roo but anymore than that woukd be too much for my small flock. I am adding pictures of the three of them but couldn't get the to slow down long enough for me to get good ones thanks to my 3yo making so much racket and playing with the Plymouth Rocks lol.
