Sore on foot, discoloured crown

[LindaO]

Yesterday we noticed one of our red stars crown had turned a grayish brown at the tips. Today when I checked on her I discovered she had a yellow sore on her food that was leaking fluid onto her feathers, and she was limping. She was active yesterday, but had gone into the far nesting box to sit today.

The coop is insulated, dry, well ventilated, but it is also close to minus 20 outside and the coop is unheated. Wondering if it could be frostbite? My other two red stars are healthy and active with bright red combs. I don't have much experience with chickens. Thoughts? I am having trouble uploading photos, will try later.

The comb discoloring might be frostbite, but her foot sounds like a separate issue. Could you take pictures of her foot? It sounds like an infection is on her foot if it’s leaking yellow fluids.

I was able to post a couple pics, not the greatest I was trying to get a photo quickly before the other chickens tried to escape the coop!

I'd start with soaking the foot in warm (not hot) epsom salt water, or plain salt water if that's what you have readily available, then using Betadyne solution, or one of the Vet sprays to disinfect it. I'd also put some neosporin type triple antibiotic on the comb a couple times a day, for a few days.

@LindaO how is this progressing?
Agrees to wash foot and take a better look,
but leave your hands off the frostbit comb.

Comb does look like it may be frostbite, I would leave it alone. It may darken more and some parts may eventually drop off, depends on how much tissue was damaged and how badly. I would use an ointment on the foot and keep an eye on it. It may also be a bit of frostbite, or may be an injury of some kind. Your coop doesn't need to be heated but if it doesn't have enough ventilation then moisture gathers and much increases the chances of frostbite. Birds with large combs are also more at risk. Feel your walls and ceiling first thing in the morning for any dampness or wetness, which means you need more ventilation. It's the birds breathing all night in a closed space that causes the moisture to build up.

How cold is your weather. I would agree with @coach723 that you are dealing with frostbite in the comb, and it also looks like it in the foot. It can take a week or more to know how serious it is. Getting a foot wet in water during freezing weather or a lot of moisture in the coop is how they may get frostbite. Do not massage either area of frostbite. Post new pictures soon if you can.
