Chicks dying rapidly with little/no use of legs before death

[ClairedeLune]

I got 25 Wyandottes from Paul's Poultry on the 8th. I am very worried, two chicks have died very rapidly. They did not move just prior to their death. If I tried to gently stand them up, they fell backwards and they looked rather like they had a seizure. I am very worried about them, because more seem to be developing symptoms. Please help! I can give more information if necessary.

maybe they are just sickly chicks and they passed the sickness among each other. separate the sick chicks from the others to keep them from getting sick. try to give them tat "vitamin" stuff in their water... idk what it's called, but they say it all the time on this site. i heard that scrambled eggs help sick chickens toom

When did they die? What type of brooder do you have them in? More info about how they're being housed and fed would be helpful.
