My chicken can't use its legs

[poetsinpompeii]

My 10 week old silkie hen is having problems using it's legs, the first time I noticed it, it looked like it was limping and finding it hard to walk, slightly falling to the side and using it's wing to try and keep it balanced, it got worse the next day and then the two following days in seemed to improve. Now it doesn't/can't even move, it stays in the same position sitting in the corner of the coop.
There is no bend in the leg at all and if it does try and stand, her legs spread out completely to the side and sometimes bend back. She doesn't talk like she used to and if she does it's quiet and deep.
Does anyone know whats wrong? And if there is anything I can do, or what should I do? Someone please help

Hate to be the bearer of bad news but it sounds like mareks disease. Silkies are prow to it, especially young birds. Google the disease and see if you recognise the symptoms.
