My three month old Cuckoo Maran is losing tail feathers and has blood on the quills. The quills are left in her but the feathers are gone. Since she is the largest bird in the flock, I don't think other hens are pulling them out. Is there any disease or parisite that would make her pull her own feathers out? Is this a normal molting occuring? Since I'm a new owner, I have no experiance to draw from. I am posting pictures. I know they are not that clear but my camera does not have a macro function. Thanks.
