All the rest of my ducks and chickens completely molted this past fall, except my one duck Spinach. He molted all his feathers except his flight feathers, they’re just raggedy sticks now. Is this a health concern? He is a Muscovy/magpie duck mule, his sister was mentally and physically disabled...
One of my ducks, Fiori, who has particularly ratty and dull feathers, hasn't molted. Her sister has, but I haven't noticed Fiori has shed any feathers. Does anyone know what might be going on?
She seems healthy otherwise.
Thanks!
