I bought a red cochin at a fed store and it grew up into a frizzle cochin we were confuzed at first, and my dad hated it (he dislikes anything with feathered feet or fluffy things,so he hated half of what we bought). He is SUPER soft and pretty,but has an attitude.
I have a cross (blue laced red Wyandotte & black Australorp) that looks alot like a blue orpington. It looks like you have it right on the colors & genders.
We know what most of our bantam assortment is but we still don't know about these two. I think that they are Partridge Cochins (just poor quality) or Barred Cochins.My mom thinks they are Gold Cukoo Marans. We have another that is brown shaded, but its picture wouldn't load.
The first one is of a pine cone with snow on it, The second is from the underside of a dogwood tree (It got reserve state at the fair), The third is of a dog in lake at sunset, the last is of a christmas tree but I moved so the lights blured.
OEG or Dutch on the chipmunk they look close to mine but are darker and have dark marking around the eye. You are right about the Golden Sebright, i have some also they love to dig the shavings everywhere!
