Chicks with bald strip on belly!

[ChcknLady]

I have 2 red sex links (2 wks old) with bald strips on their bellies. I have posted in Emergencies, etc (with pics). . . but no one has answered. Can anyone here help?

Are they picking at their bellies? Do the bellies look like they are raw? Could it be mites?

I am not sure. Hopefully someone will have an idea for you.

Some of mine had bald areas on there bellies when their feathers were coming in.
