OK - this is a lame-o question, I am sure. I had a customer in the shop last week who insisted that a neighbor of hers had at one time hens that laid eggs with blue yolks. Not shells, but yolks. I've googled around and am not finding anything helpful or solid...so I thought I'd check in with the experts. An update - our flock of four turned to 12 with the addition of 7 Araucana adoptees plus one white one that has rabbit fur rather than feathers...and strangley deformed flat, twisted toes. Poor thing can't roost, she just sorta plods around. The new birds are about 9 months old. Between her and the white Auracana with the twisted beak, we seem to be running a special needs chicken home. Anyway, the 2 flocks have fully integrated, they eat and roost and nest side by side, and all is going swimmingly. But gosh - this Blue Yolk thing has driven us to distraction. Any help is much appreciated! -b.
