What temperature to worry about waddles & combs?

Don't know if this is the righ spot to post, so feel free to move if need be.
I have 6 RIR pullets that were hatched on April 11th, so they are almost 8 months old. I read in one of my books that their waddles & combs are prone to frost bite in severe weather. I was wondering what temp you need to worry and how to treat. I have read about some people coating them with petroleum jelly. It's 30 something degrees F here right now with 20 - 30 mph N winds and it says it feels like 21 degrees F. Temps are dropping. They are predicting icy - rain. Should I go lather up the waddles & combs w/ petroleum jelly now? If not, when to worry? I also EE & Silverlaced Wyandottes same age........do they need it to?
Thanks,
Kim

I have never had any trouble with my hens. I have had trouble with my roos. They have bigger combs and there isn't good blood flow in the combs and waddles. I would put the vasaline on them if you are worried. They can get frost bit in the 30's if the humidity is high. Better to be safe than sorry

Thanks! I am worried b/c it will drop in the 20's at some point. I think I'm going to just to be on the safe side. The wind today is wicked. I keep thinking they will have kinds of stuff sticking to the vasaline. It will be interesting.
Thanks again,
