Recently I noticed one of my Buff Orpingtons had a section of her comb seemingly missing. This flock has had weird combs before. One has a really large cockscomb (and is much more assertive than other hens) and another had a curled comb that flopped to one side. However, I hadn't noticed a comb with a missing section at all until now. I've been monitoring their behavior for a while and I haven't found any bullying, but the hen in question does tend to drift farther from her flock than others. I couldn't find any blood on her comb. I think it might have been pecked off, torn during mating, or possibly a result of an attack by something. Does anyone have any ideas?
