From Cherrie Nolden on our Facebook group. Cherrie is what I would consider to be the authority on this topic:

“The thing that folks should understand is that letting chickens expose themselves to pathogens is the organic way to produce antibodies against those pathogens. They deposit those antibodies in their yolks because this is how birds transmit their maternal antibodies to their offspring (no colostrum or placental transfer involved in an egg).

These studies are all doing the antibody production via injection of an antigen into the chickens that lay the eggs. That makes it patentable. Organic approaches are free and no patent is infringed. I have used the organic approach for years, and conducted PhD research on the patentable, reductionist approach. Two of my abstracts are below, and some additional articles if folks are interested.

Parasites use IL-10 to hide from the host immune system, so my PhD research was to use antibodies against an IL-10 peptide to help the host see the parasites and develop an effective immune response.
