Mooks been losing a bit of feathers recently, I don't think he's plucking as its mostly down feathers and he even has a down feather on his neck that's just hasn't fallen out. Another reason why I think he's just molting is that he has a couple spots on him that's kinda poofy, like you see some feather popping out but its only fluff from the bottoms. If it helps I could submit a feather, I just wanna make sure he's just molting, though he's only 3 months? Isn't it a bit early for field?
Just sounds like a moult, birds lose feathers year round and their true moults are affected by numerous factors and are commonly thrown off their regular course due to artificial light, inadequate UV light, irregular seasonal nutrients, or something wrong with their health. Babies will moult out their down feathers fairly rapidly as they’re the oldest feathers, they’re baby feathers, they’re weak and they need to grow in their adult insulative feathers if they hope to survive the following months, the rest of the feathers would typically moult at around 6 months of age.
