Yes, he almost back normal this morning, i have read it could be lack of vitamins D or E, so added vitamins to their water at night yesterday and put him in another brooder with normal bulb. He was in a brooder with red lamp.
This is the article i read yesterday:

What have you done with your chick?
Pretty much the same thing. Mine was a hen chick who appeared perfectly normal until about 3.5 weeks old. She started with the walk a few steps and sit thing and she just looked like her legs were very weak. I administered a multi-vit drop for birds twice a day, and some supplemental calcium. She is a yearling now and I am keeping her because she still shows signs of weakness in the hock joints, but she is able to get around well. She was in with 6 others that had no issues, but she was not from my birds and the others were. She was the lone surviving chick from a friend's hatch, and he had no others her age so he brought her here because I had some only a day older. Wonder if the deficiency could have been in the parent stock?
