I swear this 11 week old is a rooster but a more experienced person told me it's a pullet. He said due to the dark legs and beak, it's a pullet. I think it's a roo because it's comb is obviously larger than the others and it also has feathers on its tail that are getting longer. Just the feathers on the tip are a beautiful green and a bit longer. It is a mixed breed so below, I'm going to post a picture of the roo and hen that it came from, although I'm not sure exactly which hen as they are not my chickens. Any help would be greatly appreciated because if it is a roo, I want him gone. Thanks!
