I guess if the are both cockerels it will be harder to tell as nothing to compare to?
Every breed is different and even within each breed, different lines can develop at different rates. Some cockerel combs may pinken by 3 weeks old, while others may not become as apparent until 8-10 weeks on average. If there is any chance you can get a better idea of how old they are, that would be extremely helpful. For example, my large fowl Barnevelder cockerels have combs that are pink by 3 weeks of age while the pullets remain a very pale flesh color. But, my bantam Barnevelders are generally harder to sex until around 6 weeks or so and even then I have to look at just the base of the comb as the cockerel combs are still flesh colored along the edges. My Iowa Blues are distinguishable by 4 weeks. With my Swedish Flower Hens, it is generally closer to 8 weeks before I have a true idea and, again, I have to focus on the base color of the comb as the tips are still flesh colored. But all of the pullets' combs remain completely flesh colored. So in my experience, at this age, any pink in the comb indicates cockerel. If, however, your birds are older and closer to point of lay, a pink comb on pullets would be expected. Any chance you could contact the person you got them from and ask how old they are? Do you even know if they are the same age? If they are not the same age, that can also complicate trying to sex them. Good luck!
