Helpful article on Anemia in chickens! I never knew about Anemia until a few weeks ago when a friend said her chicken had it. Thank you for the explanation, symptoms, possible causes, and the link to the other article. This has been helpful to me.
Needs more detail - as it is, it's quite short and I think it would be worth going into more detail on causes of anemia. I like your formatting (and that you gave a citation for your photo.)
