There is something going on with my adult Delaware rooster and my young RIR Roosters comb. They say a bright comb means healthyness and a dark comb means sickness. Well, both of their combs are dark one second and bright red the next. It changes quick, sometimes it takes a few minutes, but it always changes.
Does anyone know what this could mean? I have a photo of the dark comb on the RIR, but its not very good.
Its just along the points and edges of the comb though.
