My chicks arrived this morning, all alive and accounted for. Their activity is just as described on this board with one exception. Three of the chicks (out of thirty five) will fall over, looks like they are scratching their ear, and flounce around spastically, rest a moment and then do it again. Is this a balance issue, birth defect, insect problem, result of mail handling, or what? I'm not even sure they have drunk or eaten anything yet (they all look alike to me!). Please give me some knowledge!!
