The chick's crop will slowly stretch to accommodate larger feedings as time progresses. Use the cotton swabs dipped in warm sterile water to clean the chick's face and beak. Do not allow formula to build up around the corners of the beak as this can cause bacterial infections and may also result in beak deformities. Monitor the chick while cleaning to make sure it remains in an upright position. I have had chicks get so excited at feedings that they vibrate and shake all over.
Some chicks get so worked up that they flip themselves over.
This can result in aspiration and death. Once cleaned, return the chick to the brooder. If you have difficulties do not keep the chick exposed for more than several minutes. Return the chick to the brooder and begin again. After the first few attempts both you and the chick will get adjusted.
