six old chick not walking well

[tcox1963]

I have a six week old barred rock chick that isn't walking good. At first I though she hurt her leg but when she walks she sort of drags each leg. When I hold her to my chest she lets both legs stray stretched out. It has been extremely hot in WNC. I have given her (and the rest of the chickens) electrolytes in their water.I also gave her some baby vitamins incase of deficiency. I thought maybe she was too dehydrated to drink enough. I have separated her to protect her. I am also trying to keep her cool. Anyone have any thoughts? She eats fine.

Concerned momma hen.

Was she vaccinated for Mareks? Here is a good link about Mareks disease which includes certain conditions that can look like Mareks causing lameness: https://www.backyardchickens.com/a/the-great-big-giant-mareks-disease-faq
