Silkie chicken chick 6 weeks old

[Carole B]

I am raising 5 chicks in the house and this morning I have found one to be off his legs. I can see no injury. Has anyone got any ideas what could be wrong? thank you

Could you be a little more specific? What is your chick doing? Is it just laying there or is trying to move. Eating, drinking?
