I have 4 chicks that are all a week old, 2 standard size and 2 bantam. One of the bantams has what looks like a chip in the middle of the beak. It wasn’t chipped when I first brought them home so I’m thinking maybe one of the chicks pecked it. They others aren’t picking on it or at the place and it’s eating, drinking, overall acting normal and healthy. Will it grow back?
