Help I think i have a rooster

[BYC Lover123]

Hello, i am new to chicks and i bought 5 pullets from a breeder and i think one is a rooster. He is a lot bigger than the rest and its comb is bigger and redder. They are 3 weeks old and all have little bumps for there spurs.

Can you post some pictures? What breed are they? It is very possible you do have a Roo. Chicken sexing is not 100% accurate...depending on sexing method, it can be somewhere in the 80% range.

Last year we purchased 6 pullets...4 rhode island reds and 2 partridge rock. It was our first year and we didn't have experience. I remember thinking something was wrong with one of the PRocks becasue she was smaller..I wound up naming her "Runtster"lol. It wasn't until they were about 6-7 weeks that I figured out Shirley was a Rooster. We tried to keep him, but he became very mean and start trying to attack our 6 yr old. I guess that breed is one of the meaner Roos.
