Well, I'm hear to report on egg color........
She laid her first egg today and sadly it was brown. I had been prepared to be happy with "cream" since I heard that good egg color on the Barred Holland was hard to come by, but this wasn't even cream. The egg is medium brown.
Since white egg production was the reason the Barred Holland was created in the first place, this is seriously disappointing. And it is not a good Barred Rock either as it is too small and too skinny, and it is more cukoo than barred. Urch doesn't even list Barred Rocks as being one of the breeds he offers, so I don't think this was an inadvertant swap or something.
Basically, it looks like I paid $6 for a hatchery-quality "barred rock"! It's no big deal for me, a backyarder. But imagine if you had bought a whole shipment planning to breed. (Faverolle, I feel your pain !)
