I got these as 2 day old chicks from a Hatchery the beginning of May. They are both supposed to be White Wyandotte sexed pullets and are about 12 weeks old now. I suspect one of them is a rooster though! They are both the same age, but the one on the left (Snowball) is smaller than the other one, the tail feathers seem blunted, the comb has barely come in and its so pale its almost white. The other one (Eggbert) , on the right, has a long, tapered tail, the comb and wattles are almost in and they are BRIGHT red! Their behavior doesn't seem to be much different from one another, but Eggbert does seem to be less shy and always checks everything out, while Snowball tends to run and hide. Eggbert also seems to be more vocal, though I haven't heard a "cock-a-doddle-do". Can you tell me if they are of different genders? thank you!!!!!
