They are either too crowded in, too hot or both. Bobwhites are highly suseptible to cannibalism in the brooder if one of both of these is the situation.
So, start your heat at 97 degrees and ONLY use an infra red bulb as the heat and light. White light makes Bobs go bad. Place the heat off to one side of the brooder with the thermometer on the floor directly beneath the heat source. The food and water off on the other side so they have to leave the heat to get to the goods. You want cooler spots on the other side of the brooder. If bobs can not cool off a bit, they are going to kill each other. And that is exactly what they are doing. Going after each others beaks.
Give them at least 1/2 square foot per chick. Do not cover the lid with anything but a screen or wire so you have good heat and oxygen exchange. At 3 weeks, up the square footage to 1 square foot per bird.
Lay down paper towels and sprinkle crushed feed all around the floor near the brooder so they can find the feed. Dip their beaks in the water on the first day. Use chick waterers or put marbles or tiny stones in a regular water font so they don't drown. You can remove the paper towels once they figure out where the feed is kept, in a few days.
Lower the temp by 5 degrees each week for 6 weeks. If at any time, the bobs start in on each other again, lower the temp 2 or 3 degrees right then and there, and work it down from there. Cool them off it they get cranky.
Good luck and keep us posted!
You can try it and see. But keep all these rules in mind. Bobs are very touchy, unlike other quail or poultry. If the "glow" doesn't settle them down and you have added more room, temp is good, you may need to go ahead and get an infra-red bulb. Not a red bulb, but infra-red. Infra-red is a wavelength of light. They are not disturbed by it as they are with other light lengths.
