HAD TO BE CUT OFF. WHAT THE. ive had roosters get their combs frostbite. Frostbite does not spread to their heads. You can put stuff like neosporin to help heal. or Vaseline like Kwhit suggested to keep moisture out and further frostbite. But the tips of the comb will fall off on there own. Frostbite is painfull i cant amagine hurting them more by cutting the tips off.Our coop is in front of the hutch
This is how I let our birds out, by opening the flap to let the sun {when it shines} into the hutch. The coop is insulated and enclosed with a door into the hutch and the hutch is more for outdoors but completely closed in against the snow, wind, rain and other elements that could cause problems with my birds. To let birds outdoors at any time, they need to be fully feathered! If they are not, they could sicken and die. I never let my birds out in wet or snowy conditions for fear of frostbite.
Black crown on roo is dead, frostbitten tissue that has to be cut off to prevent the frostbite from reaching his head.
Frostbitten feet...
These toes have to be cut off due to severe frostbite. How is this chicken going to walk? Never put your birds, at any age, in the snow or wet conditions. The hutch I have above is well enclosed so no wind, rain or snow can get in. Even though its tarped and not insulated against cold, I have a thick layer of straw on the hutch floor that is kept dry. While the coop is insulated, strawed and has a bulb for light and a little heat.
