noticed dried blood on barred rock's combs. we have 15 chickens total, 5 barred rocks, 6 RIR, and 4 aruacanas. Barred Rocks are the only ones that have this issue, they apear to be at the top of the peck order. They seem to be in fine health otherwise.
Any ideas of what could be causing this would be helpful.
