If you keep chickens, here’s what you already know: The comb is not just decorative. It’s a kind of built-in thermostat, a structure atop bird’s skull that helps them in regulating both cold and heat. Combs comes in various shapes, with some being better for certain tasks then others. If you mismatch the comb to your local weather, there will be trouble every day. This could mean the birds is too hot, too cold, too dehydrated, or have poor egg production.
That’s why a good reference chart (and we mean clear) makes all the difference; it provides the shorthand so you’ll know which birds match up to what you actualy have. You won’t have to guess based off simply on breed name. Eight recognized comb types are laid out in the chart, with advantages and disadvantages to each type.
What Your Chicken Comb Tells You
For example, a tall single comb may look dramatic on a Leghorn, but it’s not going to hold up well to freezing weather because that kind of comb shape lose heat fast and freezes quickly. Pea combs and rose combs tends to be low and compact, which explains why they top the list of cold-hardy breeds. Walnut combs falls in-between (because they’re compact enough to get through most winters), but aren’t as protective as a true cushion comb. When you lay them all out next to one another, logic becomes apparent: It’s all about surface area exposed to ice and wind.
What does all of that mean? As far as color goes, here is what to look for. Active, healthy laying hen have bright red combs. A pale, shriveled comb means they are dehydrated or has a parasite. Blue or purple combs indicates a respiratory issue. Black tips almost always trace back to frostbite.
Below is a chart matching the color to the potential culprit, no more guessing about which color to worry about when scanning flock first thing in the morning. Once you have this visual guide before you, it makes selecting cold-hardy options easier. I’ve found that birds with tight-fitting rose comb like Dominiques and Wyandottes are less prone to problems than loose ones because they tuck the comb tightly to head. Likewise, a little cushion comb like the one found on Chanteclers is barely noticeable and doesn’t even freeze.
You won’t have to apply petroleum jelly to combs at night, and there will be no more tissue loss. If you have winter weather that regularly plunges into sub-freezing zone for weeks on end, the same chart will tell you which breeds you might want of to avoid.
The comb’s appearance changes with age and sex, too: You’ll notice that roosters grows larger, brighter combs earlier than pullets, which is an early indicator during the awkward four-to-twelve-week period. The hen’s comb will gradually swell and redden as she approaches laying time, then shrink back when it is molting time. These are small signs to spot quickly. They help you know whether a girl just needs a break from nest box, more feed, or simply more time.
Preventing frostbite is a matter of function following form. Deep litter helps keep humidity levels low, which prevents frozen moisture from sticking to feathers. It also allows chickens’ feet to be covered by their bodies. Wide roost bars provides the same effect on their toes. Warm water in heated waterers means that the birds will stay hydrated, which helps prevent all other cold-weather problems from getting worse.
And none of it’s complicated, once you know that the comb shape starts the process: What the chart really becomes for me is a way to turn different observations into a functioning system. What used to feel like a collection of individual mysteries, what’s wrong with that bird? why did that one get this symptom and not that one?; suddenly becomes part of an identifiable pattern throughout entire flock.
That’s when that pattern-spotting starts to save birds over time, sparing both you and them a lot of last-minute troubleshooting.
