In my opinion they look like they are pullets at this point, but in truth they are too young. My white silkie kind of looked like she had streamers, but she molted at about 9 weeks, and all her feathers came back before the rest of my silkies, and she is obviously a pullet at this point. I can tell that I have two cockerels, because they both have streamers a larger comb and wattles. But mine are the bearded variety. When I had the non-bearded, it took forever to find out their gender. They were easily 4 months before they had noticeable cockerel features... By 5 months they were crowing and I had to find new homes for them.
