I got three at the same time from a guy who told me they were Buff Orpingtons. I also raised 6 others from day old that I got at a local feed store, these were also buff orps.
It's legs are pretty thick too compared to the one behind it. Isn't that a sign of a roo? I have some girls about that age and none of them have combs that large or red.
He should be about 14 weeks if the age I was given is correct. When I got him he was supposed to be the same age as my other hand raised girls but he was a good bit smaller, maybe better feed. He is the same age as the other one behind him so I think roo as well.
