My hens fallen comb turning purple on the edges.

Get yourself a scale and start weighing her. Having a baseline weight has been the greatest diagnostic tool for me. When in doubt, put the on a scale. If they've lost weight, there is usually a problem, and the sooner your address the weight loss, the greater the chance of recovery. Once a bird loses 1/3 to 1/2 its weight, it's almost *impossible* to save them.

ok thanks.
