My hen came back from vacation with a black comb: should I panic
Oh, a black comb on just one side? That's enough to make anyone do a double-take and maybe chickening out on the whole chicken-keeping gig for a second. First, take a deep breath, this isn't necessarily a cluck-tastrophe. A black comb can be a sign of frostbite, a pecking injury, or even just a little fowl play from a flockmate. Since the other side looks normal, it's likely localized trauma rather than a systemic illness. Keep an eye on her appetite and energy levels, and if she's still acting like her usual feathered friend, she's probably fine. For a deeper dive into mysterious chicken ailments, our "Speckled Egg Mystery" piece might ruffle your curiosity in a good way.
My hen's comb looks like a crusty science experiment: what is this
Oh, a crusty science experiment of a comb, been there, and it's about as unsettling as finding a surprise egg in your shoe. Your Sapphire Gem's comb going from yellow-ish spots to black crusty bumps sounds like a fowl mystery that needs more than a Google deep-dive. You're smart to suspect pecking at first, but the spread to a second hen suggests something else is clucking around. Fowl pox is a strong possibility, and that would mean quarantine for both girls to stop the spread. I've seen this play out, and the "it could be this" rabbit hole is real.
