One of my BO chicks is doing something strange. They were born on 3/27. After she lays down, whenever she lifts her head up or first stands up she has her mouth open, sometimes she opens it really wide. I don't know if she is panting or what she is doing. She does not seem to be breathing heavy & she is eating, sleeping & pooping normally. Any suggestions as to what she is doing & should I be concerned. None of the other chicks are doing this.
