Frostbite!
Due to the large number of posts about chickens suffering from frostbite, we thought we'd share a case story about a chicken with frostbite to help educate and reinforce the importance of bringing a frostbitten bird to see a veterinarian.
Big Head is a young rooster who was brought to see Dr. Rebecca Gounaris at the for frostbite following a cold snap. Although all chickens are susceptible to frostbite, breeds with large single combs and wattles like Big Head are more at risk.
When exposed to extreme cold, the body will respond by constricting blood vessels, and so more distal aspects of the body will not receive decent blood flow, causing those tissues to freeze. In chickens, this is their combs, wattles, toes, feet and legs.
Affected areas of the comb and wattles will turn white with superficial frostbite and black with deep frostbite. The black color is indicative of tissue death/necrosis. Blistering may also occur. It can take several weeks before the full extent of damage is determined and if the affected tissue will heal or die and fall off.
Big Head’s case was a severe case of frostbite, since the tissue along the top of comb and edges of his wattles were black. Parts of his comb were blistering. He was prescribed carprofen to help with the pain, antibiotics to help prevent infection (which can occur within blistering or exposed tissue), and pentoxifylline to help improve circulation of blood to the distal tissues and save as much of his comb and wattles as possible. Dr. Rebecca recommended applying silver sulfadiazine (SSD cream) or aloe vera on his comb (gently without rubbing) to help provide some relief and promote circulation. It was important Big Head remained inside to prevent the area from refreezing.
