Reuters: Because chickens grow up to lay eggs faster than sheep, goats or cattle begin producing milk, researchers say, the birds could be a quicker source of biologically produced drugs to treat a range of problems, from blood loss to cancer.



Genetically engineered chickens produced consistent levels of an enzyme in their eggs, suggesting they could be used as living “bioreactors” to make proteins used in human medicine, the team at the University of Georgia and AviGenics, Inc., reported.
