Brooder cannibalism in coturnix should be rare. I'll even go so far as saying infinitesimally rare.
Please remember, I'm talking about chicks less than 4 weeks old. Not what happens when they get their freak on between 4 and 8+ weeks. That is another story.
Also please remember that this only applies to coturnix chicks, not bobs, valley, or any of the other species of game birds.
I don't use IR bulbs of any kind. Not because they are bad, just because I don't have a thermometer (Digital or other) that can accurately measure IR radiant heat. I brood (Coturnix) under a bug lite. Yes, one of those yellow bulbs you saw when you were visiting your very strange Great Uncle Joe. He means so well!
They are available in 2 or 3 different wattage's, they are low spectrum viable light, and they can be adjusted (For heat purposes) with a properly wired dimmer switch, or you can make a tinker toy setup where you move the bulb further away from the "HOT SPOT" to make it cooler.. I'm going for the $4 dimmer switch.
As Akane suggests: Coturnix chicks in the brooder should have access to high quality 25%+protein game bird feed 24/7. They are not chicken chicks!
Bean count your bird feed in about 4 weeks. You should have a 24/7 shrimp and lobster bar in your brooder. All you can eat 24/7! They actually make feeders that will do this.
Don't confuse pecking in coturnix with cannibalization pecking! They will peck at each other in the bator and brooder, but please don't confuse this with cannibalization. It is normal, and they will find a natural pecking order with out anyone's superior human intellect!
