Help! 3 day old EEs picking at ones feet

[Love my Critters!]

I just got 6 EE's from the feed store and they are in the brooder. The brooder is a 2.5 foot box by 3.5 foot box. They are all picking on one of the babies feet. They are pulling so hard that it knocks it down and the others are dragging it. The feet may be shiney? Is there anything I can put on them to make the others stop. I have a child throwing up and can not go the store until this evening to get another lamp for another brooder so I can not separate. Please give me any suggestions!

Try putting the chick in a box with another gentle chick. You can fill a thermas with warm water and cover it with a towel so they can keep warm. Good luck!
