No, no vaseline, I have added another tarp on the side, the rose combs just had black tips, the single comb has an inch or two towards the back. This will be an interesting test for them, no hens yet with any signs of frostbite.
On my own frostbites I never cut any away, watched them close, took the scab off when it was time. A strong antibiotic works better on any infection then surgery which just adds another wound to the equation. Surgery is only indicated if there is gangrene, not before.
So, Kathy, what kind and how many turkeys are you getting?
