caruncle in a muscovy is getting lighter in color and white streaked

[RebinNH]

What does it mean when a muscovy (drake) caruncle gets lighter and streaked in white? Is that a sign of some deficiency?

Is he molting by any chance? Caruncle color will lighten with a molt.

 

[RebinNH]

No. He's not.

How is the drake doing now? I've read somewhere that they do change when breeding season comes in, usually to a deep red color, and they will get pale if something isn't right, like a deficiency, or an injury....

Mine did this recently and I’m not sure if it was attributed to a drastic drop in temperature. He is free range and several new ducks showed up stressing him out plus the cold. I’ve since changed him to a more comfortable arrangement at night. I was worried it was frost bite. Anyone else have this happen?
