How do I know if a chick has mites?

[beylabean]

I have just purchased 11 chicks. They are straight run and a couple different hatches (1 Sexlink 4 days old, 6 SLW that are 3 days, 3 SLW day olds and 2 SLW that are 2 weeks old) All are in the same brooder box, but I noticed that one of the 2 week olds is scratching at his/her head and picking at it's feathers. Not sure what to look for if it were to be mites.
I do have DE sprinkled in the brooder just in case. But just thought I'd ask and see if I can catch it before it spreads, if it is in fact mites.
Maybe I'm just being a paranoid first timer

Any help appreciated

Please don't put DE or any thing else in there UNLESS you have seen mites. They can be seen with a good magnifying glass. The chicks will do a LOT of scratching. Pushing out those new little feathers is itchy business. Enjoy your babies! Also, it's important to have that brooder cool enough. They should have at least 1 sq. foot per bird, and be able to get away from the heat to room temp or below at the far end of the brooder.

AY...Why is there conflicting info on DE? I read that it was good to use! ?

It's very hard on the lungs, and not terribly effective on the target organisms.

Ok! Thanks for the info! I will check them over this afternoon and clean out the brooder
