Should I be concerned?

[BunsNChicks]

One of my chickens randomly died today. When I found her she didn't look like she had an injuries (no blood). She was only 1 yr old. Any ideas how she could have died? Oh, also I let them free range during the day. Should I be concerned about the rest of my flock?

The chicken died...and only thing it was doing differently that day was sleeping on the ground inside the coop while everyone else was free ranging. I have brought in a couple of new birds over the last 3 weeks...not sure that is the cause tho because today I noticed a TON of mites crawling on the nest box of one of my broody hens. Is there anyway to treat naturally or do I have to use insecticides?
