We have 7 straight-run Buff Orpington chicks, about 4 weeks old. I THINK they are all females. Does anyone have any pictures of male and female B O chicks at 4 weeks of age? (showing the comb). We also have 3 straight-run Ameraucanas and I know that 2 are females and 1 is a male. Unsure with the Buffs... any help would be appriciated! Here is a pic of one... this one seems to have the largest comb of them all.
