Lovely ladies!Essentially. I am pretty certain they will be fine.
As I remember you flocks combs, none of them are overly large. I never put Vaseline on Patsy's comb even though I did Daisy's, the greatest hen ever. Patsy never lost any comb to below 0°F temps, nor did Lilly. I am debating Hattie's but it is not much bigger than Patsy's. Daisy's comb was enormous.
Frankly after I put this collage together, I don't plan to even do Hattie's comb. Its smaller than Patsy's.

Maggie has a pretty floppy comb. On the other hand she almost always buries her head in her feathers when she sleeps.
