leghorn chicks-male or female

[crtyjlee]

My husband brought home some chicks from the feed store and they werent sure which breed they were, but i believe they may be leghorns. One is about 4 weeks old and the other about 6 weeks. They are starting to show some differences such as comb size. They both stand more upright than the rest of the chicks, and i have noticed that their tails stick straight up more like a rooster. Does anyone have any hints or opinions on the sex of these two chicks? thanks!!

The first one may be a pullet, but I'm pretty sure that the second on is a cockerel, based off of the large red comb. Leghorns do develop combs faster than other breeds, but that comb is quite red for the age.
