Can I bandage a comb?

[earlybird10842]

We have an older, mostly blind hen whose comb I found bleeding this morning. The cold has kept the chickens in their small coop for almost a week, so I am not surprised, but I want to keep this from happening again. Is there a way I can bandage it so the other hens don't see blood and peck more?

It seems it might be difficult to get one stay on. Do you have blue Kote? If you have and only have a spray you could spray it on a q tip and dab it on?? If you have a sick bay, isolate her in the coop?
