Based on what I can see, I would guess partridge Wyandotte, though they usually have yellow legs.
Just a side note, chickens don't get colds like we do, they get upper respiratory infections which can make them become permanent carriers depending on the infection...
Yeah she has a mycoplasma infection, my vet gave me Tylan to treat her and my others with. Being super new to chickens, (only had her 16 days) I didn't realise she was ill until it was too late an my other chickens started to sneeze and wheeze too
A barnevelder should have a single comb, do you know if she originally came from a hatchery? If so, that would explain the pink legs and light ground color. Regardless, I think that gold color is really pretty.
