Researchers have genetically modified chickens able to lay eggs containing drugs against arthritis and some cancers. Medications are 100 times cheaper to produce when they are laid than when they are manufactured in factories. Researchers believe that over time, production can be increased to produce drugs in commercial quantities.

"Chicken production can be 10 to 100 times cheaper than factories. We therefore hope that our overall manufacturing costs will be at least 10 times lower, "said [Dr Lissa Herron, of Roslin Technologies in Edinburgh].

Many diseases are caused by the fact that the body does not naturally produce enough of a certain chemical or certain proteins. These diseases can be controlled with drugs containing the deficient protein. These drugs are synthetically produced by pharmaceutical companies and can be very expensive to manufacture.
Dr. Herron and her colleagues have been able to reduce costs by inserting a human gene – which normally produces protein into humans – into the part of the chicken's DNA involved in the production of white in chicken eggs.
…
Professor Helen Sang, of the Roslin Institute at the University of Edinburgh, said: "We are not yet producing drugs for humans, but this study shows that chickens are commercially viable for the production of proteins adapted to humans. drug discovery studies and other applications in biotechnology.
