One of our fifteen-week-old barred rocks was bokking so loudly last evening that we went out to see what was going on. All seemed to be ok, though the chicks were all in that alert "what was that?" posture. Today Greta is hoarse, just a squeaky weak voice. Is that normal? Will she be ok? As a side note, could she have been trying out her future egg song at her tender age? I'd appreciate some of your collective experience.
