would a rat wipe out a whole bunch of chicks or just one

If you are concerned about rats, then put out traps around the brooder. They can eat chicks, but it's possible that they have another source and will leave yours alone.

Either way, you'll be able to sleep better knowing that the traps are out.

Agreed on all counts. Rats won't hunt unless they were seriously short on food. The laziest option first is the ratties way. XD
