Already afraid it could be a rooster....

[ChickenPeep]

I have two 2 1/2 week old chicks that I got from orscheln farm and home. They are (supposed to be) black sex links. However one looks to be developing a comb and wattles. They are not red yet but they are there. I absolutely cannot have a rooster and if I do I need to figure out what to do oath it ASAP. I know how sex linking works but I'm concerned that somehow another breed could e gotten into the mix. What do you think?
Here it is

And here's the other BSL for comparison (same age)

No comb wattles or white spot on head probably pullet.

Some hens develop faster than others. I would say they're both pullets.

2 1/2 weeks old is young to determine. They're easier to tell around 4-6 weeks.
