Can a color sexed pullet really be a cockerel?

[Mcook512]

I got 3 ISA Brown day old chicks. They are now 4 weeks old. One (the chick on the left) was the darkest red, definitely indicating pullet. She didn’t get her tail feathers for a full week after all the other chicks, and was much slower to develop wing feathers. I had read males are slower to feather, but being a color sex chick I didn’t think much about it. Today, I noticed how much larger her comb is compared to the others. I did a little research, and found out only the 1st generation is color sexed. Could I possibly have a little cockerel?

IF it's an ISA it IS a pullet.....and nothing looks alarming about the headshot.....but, seeing the whole bird would allow us to determine if rather than an ISA it is a nonsexlinked red breed, which would negate the color sexing matter.

Were the from a hstchery/retail source or private person? The former will only be first generation.....the latter are sometimes folks who dont understand breeding isa to isa does not = more isa

About what I was going to say.

I got them from TSC (Hoover Hatchery)

TSC is notorious for messing up on chicken breeds.

Do you have a full body picture?

This chick has been slower to feather and doesn’t have as many feathers on the head/neck

Pullet....sex link, ie isa

Looks like a red sex link pullet.
