You will need a thermometer for checking the temperature of the formula. I use a battery operated thermometer with a LCD readout, they can be found at most kitchen supply stores. Do yourself a favor and have a back up thermometer and spare batteries on hand. A clean wash cloth or hand towel will help provide a suitable work surface. I use plain white cloths that can stand up to hot water in the laundry.
Paper towels tend to slip and slide allover the counter top.
A shallow bowl will be needed to hold warm water to keep the formula warm. I use glass bowls that can be washed in very hot water with bleach or disinfectant. Cotton swabs such as Q-tips are used to help clean the chick's face and beak after feeding. Make sure you get the type with a nice compact tip. If they are too large you will not be able to fit them into the chick's mouth.
