If I were to take a guess, I think I will be getting a rooster. After all, I think its comb is growing and it is quite prominent now at 4 weeks old. Besides that, it seems more bolder compared to my other hen (ie. its older sister) when it was a chick. My wife do notice that it is more daring and not hide when she walks near the cage to take a peek at it. Also, it always jumps and claw at my hands when I am changing the feeding dish and water cup.
Statistically, my chances of getting a male chick is now higher now since I have had 2 females in a row.
Roosters or hens, I love them all. I just takes what's given.
