Chicken cannot walk or stand up.

[tjscorp]

I have a batch of 50 chicks that I bought from a local store just over 2 weeks ago. A few days ago, one of them started to waddle about as if it were having difficulty walking. It kept getting worse until eventually she could not walk at all. She just sits there with her legs stretched out in front of her and even if I try to help her up, she falls over on her back side with her legs stretched in front of her. She cannot even stand up to go and feed and i need to carry her to the feeders and drinkers manually myself. She does not seem to be injured as she has been indoors the entire time. Her legs still do flex, I have tried manually flexing her legs and massaging her, but she still goes back to the fully extended leg posture that she prefers. What could this be? Please help.

I would suggest that you try supplementing riboflavin (vitamin B2). Deficiencies can cause curled toes and hock sitting, which from your description it sounds like she may be doing.
That chick may have been deficient while developing in the egg, but also a good idea to check your feed mill dates and make sure you have fresh feed as the vitamins degrade with time. B vitamins are water soluble, so any extra will be excreted in waste, so overdosing isn't really a concern. You can use a human B complex tablet if needed , give 1/2 a tablet every day for a couple of weeks, and grind it up and put in some food for it to eat. Literature below says two 100 ug doses.
