Help - What causes bloody spots on wings and tail of baby chick?

[faith0428]

I just went out to check on our 4 chicks (approximately 3 weeks old) and something is up with one of them. On it's wings and tail (where the adult feathers are coming in) there are bloody spots and it is pecking at itself. The other chicks are pecking at it too. Any ideas what it might be? It is appearing pretty normal - still eating and drinking. I have separated it from the other chicks for now, as they all appear fine. Don't think I can submit a picture since I'm new to the forum, but could probably email if you want to message me your address.

I also just uploaded the photos to Flickr. If I did it correctly, you should be able to see the pictures here http://www.flickr.com/photos/faith0428/sets/72157626499475961/

Thanks!

Once chicks see blood they will keep pecking I would put a red lighbulb on that should help put some blue kote on that it will stop the others from pecking or let her heal and then put her with the others.
