Can a chicken go through there juvenile molt and then right into there winter molt? I have 2 Americana hens that started losing their feathers directly under their beaks about 6 months ago and still have not regrown them. I do not see any type of lice or mite. I am mostly concerned because of the winter months, they have a heat lamp plenty of water and get layer every day. What should or can I do and couple of my other hens are molting but in the back end.
