Hi everyone, I am new to raising chicks, I ordered 15 pullet and got 17 they are now 2 weeks old they are all doing good except for 1 she was fine then one day I was checking on them and she seemed extremely tired and isolated herself I put her in a kennel by herself to watch her she would not eat or drink the next day she could not walk I started giving her drinks through a dropper pedialight mixed with water every 30 minutes to 1 hour. I am also giving her vitamins poly vi solution without iron days later she seems to be more alert but still cannot walk she can move her legs but can't walk or even sit up. Anyone have a clue what's wrong with her? Anything I should be doing that I am not? Please help.
