needs to molt

[ravenseye57]

My favorite hen, a two year old red star named Maverick, is looking terrible but hasn't molted. All of the hens that I got at the time I got her have nice new feathers, including my other red star - though she also was slow to molt and is just finishing up hers. Mav has also recently been eggbound, which I think may be because she never molted this winter. I "rested" her under low light all winter, which worked on the others that needed to molt, but not her. Should I be worried? Any suggestions?
