I'm pretty sure I know my answer already, but since I'm not familiar with this breed, I thought I'd ask anyways. These 3 silver laced wyandottes are 5 wks old in this picture. The combs for the 2 on the left turned red at about 2.5 wks old, lol. the one on the right is red now, but it's not as dark and it didn't redden up until 4 wks or so (not sure if this makes a difference). The legs for all 3 look the same to me.
