My female muscovy seems to be molting. She loses some of her body feathers (not flight feathers). I think she also molted some of her tail feathers. Every day I find new feathers dropped in their pen and coop. Isn't it too early for her to molt? She is 5 months old and the weather is quite cold here at this season, about 46-48 F during daylight and about 40 F at night. They never fight or pick on each other with her mate and I always use some powder for parasites when I change the straw in their coop so I'm pretty sure it's nothing like that. Is this normal at this season? I guess she is close to laying age and she might be getting ready for it after she finishes her molt?
