Hen sitting with feet in front of her and falling over

[K R 2709]

My 1 year old Banty hen has been acting really odd. She is very unsteady on her feet. She backs up and starts to fall over at random times or when she is approached. She is normally quite agile and friendly. I also found her in the coop today sitting on her rear si her feet outstretched in front of her. She had a minor lice infestation recently and has been treated so there aren't any more except for eggs (waiting for them to hatch so that they can be gotten rid of too). She also had an impacted crop recently. She is a very sweet hen but I'm surprised that she hasn't died yet as she seems to lack the instinct to eat grit. This is her second impacted crop. Any ideas on what it could be and possible treatments? Any advice is muchly appreciated.
Thanks

Could she have wry neck or Mareks disease? Did she have a Mareks vaccine? Do you keep your grass clipped fairly short because that can cause impacted crop which leads to sour crop. I would start some vitamins in the water in case of vitamin deficiency. Here are some links to read on Mareks and wry neck:

Thanks what vitamins would be useful for her? She has just gotten over an impacted crop. Could she still have some form of crop issue even though she appears to be all better? I will read the links on thanks again

Poultry vitamins would be the best. Avian Super Pack 1/4 tsp per 5 gallons of water (available at Jefferspet.com online.) Rooster Booster sell vitamins at many farm stores. The most important ones are thiamine (B1,) Vitamin E, and selenium which can be found in eggs, low sodium canned tuna, ground Brazil nuts, and sunflower seeds. The first link has vitamin dosages if you want to follow those. Slow moving crops can be common will many diseases--Mareks disease, coccidiosis, and others.

Thanks for the help I have fed her tuna, sunflower seeds and some vitamin E. How long do you think it will take for the Vitamins to take effect if it is a Vit. Deficiency? I also have women's centrum one a day vitamins. If I feed a part of one of those to her (crushed up) do you think that it will help?
Thanks
