ok I should know this but can some one please tell me what age the pointy feathers on the hackle show up? I think I have 2 blue orp pullets but my friend thinks cockerels. They are 6 weeks and begining to get a little color in the comb but I see no pointy feathers in the hackles. No pictures available and I dont want to bring them home if they are boys just so I have to get rid of them. So by 6 weeks I should be able to see the pointy feathers right? no?
