Bones are a highly complex tissue capable of adapting to changes in muscle usage through specialized cells which respond to mus-cle strain. As such, the way in which birds utilize their wings has a direct impact on strain production of the flight muscles, and sub-sequently the keel bone to which the muscles anchor. Currently, adaptations of muscle and bone in response to a decrease in wing use is unknown in laying hens. Therefore, the first study (Chapter 2) sought to investigate if a loss of flight feathers (reduction to wing area) would reduce wing activity.
