I hope she keeps recovering even if it is a little at a time because she is just the sweetest little girl!!! I don't know for sure what had happened to her but 2 weeks ago she was fine in the morning and when I got home that night her left leg was paralyzed and her Right leg was paralyzed by the next day. She is not sick in any way. Eating well, drinking well, poos are normal. None of my other chickens have any symptoms like this. I don't believe it is mareks at all and the only thing I could think it might be is she might have been eating more than her fair share of scratch and has a vitamin deficiency.
doesn't sound like a vitamin deficiency to me. you can give her poly vit's for babies. Sratch is considered a treat so she should only get a bit. Mareks usually has one foot extended out , make sure there is no mold!!!!have u posted in emergancy section? some vets stroll through postings.
Thanks, yes I did and most were saying a deficiency as well. I did take her to the vet yesterday and they don't know either. I thought mareks spread to others in the flock but the vet there said no, it can affect only one???
I have had her vitamins ever since she was born but she is a very picky eater and dainty. She takes little tiny bites of food, talks for awhile, then a couple of more small bites and it takes her forever to eat. Maybe she just wasn't eating enough and with the scratch during the cold snap it put her so far down nutritionally??? She has gotten even thinner but she is starting to pick up on eating since yesterday and will eat the parrot food much better than the chick feed. But the vets said mareks cannot be ruled out yet.???

make sure you have her quarentined. i don't mean to sound like a bummer but she will get all your chickens sick if it is mareks. the ground will be contaminated also i really pray it's not that!!!!! i still think poison............. i hope she gets better really soon! your ag department usually will have a state vet who will come out. don't know if you tried that but they can drawl blood & run tests for free. Hope she gets better how about worms in her poo? how is the poo looking...sounds gross but it can help rule stuff out......
your vet is a dunce......sorry, please read this!!!
Marek's disease is a highly contagious viral neoplastic disease in chickens. It is named after József Marek, a Hungarian veterinarian. Occasionally misdiagnosed as an abtissue pathology it is caused by an alphaherpesvirus known as Marek's disease virus (MDV) or gallid herpesvirus 2 (GaHV-2). The disease is characterized by the presence of T cell lymphoma as well as infiltration of nerves and organs by lymphocytes. Viruses related to MDV appear to be benign and can be used as vaccine strains to prevent Marek's disease. For example, the related Herpesvirus of Turkeys (HVT), causes no apparent disease in turkeys and continues to be used as a vaccine strain for prevention of Marek's disease (see below). Birds infected with GaHV-2 can be carriers and shedders of the virus for life. Newborn chicks are protected by maternal antibodies for a few weeks. After infection, microscopic lesions are present after one to two weeks, and gross lesions are present after three to four weeks. The virus is spread in dander from feather follicles and transmitted by inhalation.
There are five syndromes known to occur after infection with Marek's disease. These syndromes may overlap.
Classical Marek's disease or neurolymphomatosis causes asymmetric paralysis of one or more limbs. With vagus nerve involvement, difficulty breathing or dilation of the crop may occur. Besides lesions in the peripheral nerves, there are frequently lymphomatous infiltration/tumours in the skin, skeletal muscle, visceral organs. Organs that are commonly affected include the ovary, spleen, liver, kidneys, lungs, heart, proventriculus and adrenals.
Acute Marek's disease is an epidemic in a previously uninfected or unvaccinated flock, causing depression, paralysis, and death in a large number of birds (up to 80 percent). The age of onset is much earlier than the classic form, birds are four to eight weeks old when affected. Infiltration into multiple organs/tissue is observed.
Ocular lymphomatosis causes lymphocyte infiltration of the iris (making the iris turn grey), anisocoria, and blindness.
Cutaneous Marek's disease causes round, firm lesions at the feather follicles.
Atherosclerosis is induced in experimentally infected chickens.
Immunosuppression Impairment of the T-lymphocytes prevent competent immunological response against pathogenic challenge and the affected birds become more succeptible to disease conditions such as coccidiosis and "Escherichia coli" infection . Furthermore, without stimulation by cell-mediated immunity, the humoral immunity conferred by the B-cell lines from the Bursa of Fabricius also shuts down. Thus resulting in birds that are totally immunocompromised.
 DiagnosisThe demonstration of nerve enlargement, especially with the ischiatic nerve along with suggestive clinical signs in a bird that is around three to four months old is highly suggestive of Marek's Disease. The presence of nodules on the internal organs may also suggest Marek's disease but further testing is required for confirmation. This is done through histological demonstration of lymphomatous infiltration into the affected tissue. A range of leukocytes can be involved, including lyphocytic cell lines such as large lymphocyte, lymphoblast, primitive reticular cells and occasional plasma cells as well as macrophage and plasma cells. The T-cells are involved in the malignancy, showing neoplastic changes with evidence of mitosis.
The lymphomatous infiltrates need to be differentiated with another condition that affects poultry known as Lymphoid Leukosis as well as an inflammatory event associated with hyperplastic changes of the affected tissue.
 PreventionVaccination is the only known method to prevent the development of tumors when chickens are infected with the virus. However, administration of vaccines does not prevent transmission of the virus; i.e., the vaccine is non-sterilizing. However, it does reduce the amount of virus shed in the dander and hence reduce horizontal spread of the disease. Marek's Disease does not spread vertically. The vaccine was introduced in 1970. Before that, Marek's disease caused substantial revenue loss in the poultry industries of the United States and the United Kingdom. The vaccine can be administered to one day old chicks through sub-cutaneous inoculation or by in-ovo vaccination when the eggs are transferred from the incubator to the hatcher. In-ovo vaccination is the preferred method, as it does not require handling of the chicks and can be done rapidly by automated methods. Immunity develops within two weeks.
The vaccine originally contained the antigenically similar turkey herpesvirus, which is serotype 3 of MDV. However, because vaccination does not prevent infection with the virus, the Marek's Disease virus has evolved increased virulence and resistance to this vaccine. As a result, current vaccines use a combination of vaccines consisting of HVT and gallid herpesvirus type 3 or an attenuated MDV strain, CVI988-Rispens (ATCvet code: QI01AD03).
I Still think it's something else!!!
